An American emblem that does not settle down

Georgia O’Keeffe’s Cow’s Skull: Red, White, and Blue confronts the viewer with a front-facing skull, its long horns extended across a field of red, blue, white and black. The object is recognisable at once, yet the setting remains uncertain. Nothing establishes a table, wall, horizon or measurable distance, so bone and coloured bands operate between still life, sign, suspended relic and monumental presence.[1][2]

The title invites a national reading before the picture has been examined. Red, white and blue evoke the United States, and O’Keeffe later recalled deciding to make an “American painting” that people would notice.[2] Yet the composition is not an American flag: its bands are vertical, blue occupies most of the field, a black stripe runs through the centre, and no stars appear. Recognition begins the interpretation but cannot complete it.

This productive instability explains why the work has served so many accounts of O’Keeffe—as a painter of New Mexico, an American modernist, a maker of icons and an artist alert to the publicity surrounding her career. The skull can suggest toughness, mortality, religious structure or desert beauty, but each association has a different evidentiary status. The canvas becomes richer when those levels remain distinct rather than merging into a single patriotic slogan.

Identifying the Met painting

The Metropolitan Museum of Art owns the oil on canvas as object 52.203, Alfred Stieglitz Collection, 1952. It dates the work to 1931 and measures it at 39⅞ by 35⅞ inches, or 101.3 by 91.1 centimetres.[1] Access O’Keeffe assigns catalogue raisonné number 773 and records the same medium and dimensions, securely separating this nearly square canvas from several other skull paintings made in the same period.[2]

The catalogue raisonné title is Cow’s Skull, Red, White and Blue, based on the Whitney Archive. Downtown Gallery records supply variants with parentheses, an ampersand or a dash, while O’Keeffe’s Abiquiú notebooks omit one comma.[2] The Met’s Cow’s Skull: Red, White, and Blue supplies the colon and serial comma used here, so punctuation records archival and institutional practice rather than a change of object.

Marks occur on the cardboard backing rather than the painted front: an “OK” inside a five-pointed star, the date 1931, a title inscription, An American Place codes and a later box number.[2] These practical traces connect studio, gallery and collection handling. They should not be turned into hidden iconography, although the star-shaped monogram is an intriguing material counterpart to a painting whose colours invite national association while withholding flag stars.

A skull modelled through damage and light

The skull is shown frontally and approximately symmetrical, but weathering prevents perfect bilateral order. A long vertical seam divides the forehead, fine cracks branch into the broad upper plates, and the lower face breaks into irregular openings and thin projections. Pale cream replaces a uniform white, with grey, taupe and brown deepening the eye sockets, nasal cavity and torn edges until emptiness gains weight.[1][2]

The horns extend almost horizontally and nearly touch the side boundaries, making the skull wider than the central body suggests. Their upper edges rise gently from the crown before tapering into rounded tips, while their lower edges curve more sharply into the cranium. This span stabilises the composition like a crossbar, yet minute differences between the two sides preserve the specificity of a once-living animal rather than an abstract diagram.

Below the forehead, cavities multiply and overlap. The dark central opening continues visually into the black background stripe, making it difficult to locate the exact point at which bone ends and pictorial field begins. O’Keeffe’s precision lies in this controlled uncertainty: jagged contours are carefully described, but their values connect them to the structure behind, so anatomical damage becomes an organising system for the whole canvas.

A striped field rather than a literal flag

Narrow red bands run down both outer edges. Between them, a broad blue field is interrupted by tapering white zones that widen towards the bottom and by the black central bar descending from the top. The blue also changes internally, shifting from deep turquoise and slate to lighter cyan along the folds, so the backdrop is neither a flat colour chart nor a neutral support.[1][2]

The painted field resembles draped fabric because diagonal tonal changes imply creases, especially on the lower right and along the left white-blue transition. The legacy page turns this appearance into certainty by calling the background a cloth. No object record consulted identifies an actual textile model, and no public technical study maps its construction; “fabric-like” or “draped” therefore describes the image without inventing a studio prop.

Nor do the colours reproduce flag geometry. The United States flag of 1931 organised alternating horizontal red and white stripes around a blue canton containing stars, whereas O’Keeffe’s design is vertical, centrally black and largely blue. Her title and later statement make national reference explicit, but the formal departures transform that reference. The work behaves as an invented banner, not a transcription of a federal symbol.

The blue appears to recede behind the pale skull, but soft value shifts also make it fold forward at the lower sides. White zones can read as illuminated cloth, open space or broad rays converging behind the object. Against them, the skull’s cream surface remains visible because O’Keeffe separates adjacent whites through temperature and texture rather than through a continuous dark outline.

Red performs a different task. Confined to the lateral margins, it frames the blue field and intensifies the bone’s pallor without spreading into the anatomical form. The narrow bands also prevent the horns from floating into an unlimited sky. Colour establishes a shallow, bounded stage whose solemnity depends on restraint: strong primaries are present, but black, grey and uneven white complicate any cheerful patriotic palette.

No published conservation report for CR 773 identifies pigments, ground, preparatory drawing, varnish or treatment history.[2] Technical findings from Cow’s Skull with Calico Roses show that O’Keeffe sometimes developed neighbouring forms side by side on pre-primed canvas while leaving small gaps and portions of ground visible, but those findings belong to CR 772.[6] They offer a comparative question, not evidence that CR 773 was made identically.

O’Keeffe’s deliberately noticeable American painting

O’Keeffe’s fullest explanation appeared retrospectively in her 1976 book. She recalled hearing men in the East discuss the Great American Novel, play and poetry while seemingly unable to imagine a Great American Painting; as she worked on the skull against blue, she decided to add red stripes and make a conspicuously American picture.[2] The recollection ties composition to ambition, irritation and humour rather than to passive national devotion.

Her phrase “they will notice it” is crucial because it makes reception part of the design. Red strips at the edges work like visual punctuation, converting a New Mexican bone into a challenge addressed to eastern cultural authority. O’Keeffe was not simply illustrating a settled national identity; she was claiming that her own subject, scale and colour could enter a debate whose terms had been defined largely by male writers and artists.

The account was written decades after the painting, so it should not be treated as an untouched transcript of every 1931 decision. It nevertheless belongs to O’Keeffe’s sustained management of her work and is corroborated by the colours and archival title.[2] Its tone guards against a flat reading: the picture is American by declaration, yet its declaration includes parody of grand cultural formulas and awareness of how novelty attracts attention.

The Great American Thing and national modernism

American modernists around Alfred Stieglitz repeatedly debated whether advanced art could emerge from local experience without merely following Europe. The National Gallery’s scholarship on O’Keeffe’s Black White and Blue describes this period as a critical turn towards sharper, larger and more focused forms after her first New Mexican seasons.[5] CR 773 converts that formal ambition into an overtly national proposition through its title and palette.

The joke about a Great American Painting also responds to the atmosphere in which Cézanne and European modernism dominated artistic seriousness. O’Keeffe knew the Midwest, South, East and Southwest and presented that range as grounds for imagining the country beyond New York.[5] The skull is therefore local material pressed into a national argument, while the bold symmetrical design makes the argument legible without requiring narrative action.

Calling the result national does not make it culturally comprehensive. A cow skull from New Mexico, displayed in a Manhattan gallery and framed by national colours, cannot stand transparently for every American experience. Its authority is constructed through O’Keeffe’s travels, collecting and career position. The painting is most historically revealing as a proposal about American art, including the exclusions and self-conscious ambition such a proposal entails.

Drought, Depression and evidentiary restraint

O’Keeffe began painting animal skulls at the opening of a prolonged drought era. Federal climate history describes the episode extending from 1928 into 1942 and the 1930s Dust Bowl as the most consequential meteorological and agricultural drought in the United States historical record.[11] Dry conditions, economic collapse and livestock mortality form an unavoidable backdrop, but CR 773 does not document a named ranch, dead herd or particular storm.

The Art Institute records that O’Keeffe collected the cow skull used in Cow’s Skull with Calico Roses in New Mexico during summer 1930 and shipped bones east to paint the following year.[6] Because CR 772 and CR 773 depict closely comparable skulls, they illuminate a shared studio moment. The public records consulted do not conclusively prove that the identical physical specimen appears in both, so that tempting equivalence should remain a possibility rather than a fact.

The legacy page turns drought into a simple emblem of national endurance. That reading matches later museum language about the strength of the American spirit, but it compresses historical disaster into uplift.[1] Drought caused ecological and economic damage unevenly across regions and communities. O’Keeffe’s bleached object may register survival, yet the painting’s solemn stillness also permits vulnerability, loss and environmental pressure to remain visible.

Cattle and the longer Southwest

A cow skull is not a timeless or purely natural product of the New Mexican desert. National Park Service history records that Spanish colonists brought cattle into New Mexico in 1598; livestock economies then developed through colonial land grants, missions, Hispano ranchos, Indigenous labour and later American expansion.[12][13] The animal form therefore belongs to a layered history of work, property, food and ecological change.

This context does not convert CR 773 into an illustration of colonial ranching. It corrects the easier notion that a skull simply emerged from an empty wilderness as an eternal American symbol. Cattle were introduced, raised, traded and moved by people, and ranching reshaped land relations. The bone’s weathered beauty can coexist with that historical materiality rather than replacing it.

Contemporary O’Keeffe Museum interpretation also locates the landscapes around her New Mexican homes within continuing Tewa homelands.[18] CR 773 contains no identifiable landscape or human figure, so it cannot specify a community through sight alone. Yet the broader caution remains relevant: collecting in the Southwest occurred within inhabited territories whose histories exceed the solitary artist-and-desert story through which O’Keeffe has often been marketed.

In a December 1931 interview, O’Keeffe linked skeletal remains and flowers whenever she imagined the desert. She admired the whiteness produced by exposure to sunlight, had begun gathering bones the previous summer and combined them with artificial blooms to express her experience of the region.[3] The statement places aesthetic attraction, collection and transformation before later symbolic explanations.

The bones travelled. O’Keeffe spent extended summers in New Mexico, then returned east for winter exhibitions, carrying or shipping objects that could be studied in New York.[4] CR 773 joins geographically separated experiences: a weathered animal remain from the Southwest, an eastern studio and a red-white-blue challenge to metropolitan discussions of national culture. “New Mexico painting” therefore describes its source and exhibition frame, not its place of execution.

The Metropolitan Museum’s 1984 study locates the actual painting campaign at Lake George in October and November 1931 and says the cow skull was among bones O’Keeffe had shipped east the previous year intending to paint them.[22] That chronology converts a general mobility argument into an object-specific making history. New Mexican collection, Lake George execution and New York exhibition were separate stages, so the finished icon emerged through seasonal movement rather than direct transcription before the desert object.

By 1939 O’Keeffe explicitly treated sun-whitened bones as personal emblems of the desert, finding them curiously more alive than furred animals in motion.[3] That later statement clarifies why close observation does not amount to morbidity alone. The skull concentrates what she found keen and enduring in the region, although “symbol” here remains personal and open-ended rather than a fixed public code.

CR 773 emerged within a concentrated group rather than as an isolated emblem. Cow’s Skull with Calico Roses, CR 772, centres a pale skull and two white artificial flowers against layered pale material and a dark vertical strip.[6] The near sequence of catalogue numbers and shared first exhibition invite comparison, but differences in format, surrounding colour and floral addition give each work a separate visual argument.

Horse’s Skull on Blue, CR 776, sets a narrow, elongated skull against visibly draped blue fabric, while Horse’s Skull with White Rose, CR 777, combines a horse skull and single bloom on black.[7][8] These variations test frontal presentation, background, flower, scale and species. The fabric is explicit in CR 776’s owner description, which makes the absence of equivalent documentation for CR 773 especially worth preserving.

Cow’s Skull on Red, CR 799, broadens the cow skull horizontally against deep red, black and tan and is dated 1931–32.[9] Across the group, O’Keeffe does not repeat one stable meaning. Bone can meet national colour, artificial or natural-looking flowers, dark void, blue drapery or red field, allowing formal relations to produce different associations before any symbolic label is imposed.

The horizontal horns and long central face create a cross-like silhouette, strengthened by the black vertical stripe behind the skull. National Gallery scholarship places CR 773 among ambitious New Mexican works connected formally to the large crosses O’Keeffe had painted after seeing them across the regional landscape.[5] Comparison with Black Cross of 1929 makes the compositional echo visible without requiring the skull to become a literal crucifix.[14]

O’Keeffe described New Mexican crosses as a dark veil of the Catholic Church spread over the landscape and remembered one large wooden example held with pegs.[14] Her language records the force of Catholic presence, but it is observational and historically complicated rather than a personal confession of faith. No source examined supports the legacy page’s claim that she was a staunch Christian or used CR 773 to affirm America’s Christian identity.

The Crucifixion remains a possible viewer association because skull, cross shape, central axis and death have long religious histories. It becomes misleading when converted into documented intent or when the animal is mistakenly called a human skull, as the legacy page does in its final paragraph. The object is explicitly bovine; the cross-like structure can be analysed as form and reception while theological certainty is withheld.

The Met’s 1984 bulletin exemplifies that reception history: it called the skull almost a sacred relic, proposed that the vertical behind it might be a tree or easel, and argued for subliminal religious undertones.[22] Those claims are interpretive, not findings from a technical examination. The black bar visibly completes a cruciform scaffold, but neither its imagined studio referent nor a devotional programme can be confirmed from the published object record, making the older museum reading valuable evidence of canonisation rather than settled intent.

Death, vitality and transformation

In January 1932 Henry McBride reproduced the painting under Death and Transformation, while Elizabeth McCausland used Life and Transformation in another newspaper. The catalogue raisonné says Alfred Stieglitz assigned both titles.[2] The reversal from death to life exposes the picture’s interpretive range and shows how dealer-generated naming could guide early reception beyond O’Keeffe’s own red-white-blue title.

The skull plainly testifies that an animal has died, but its bleached surface, extended horns and carefully balanced placement give it a force exceeding abjection. O’Keeffe later insisted that desert bones seemed keenly alive to her.[3] That does not erase death; it explains why the picture transforms skeletal residue into a commanding visual presence rather than presenting it as biological waste.

“Transformation” also describes the painting’s formal operations. A found object becomes an icon-sized image; cavities merge with a black stripe; national colours become an invented banner; and a ranch animal’s remains enter elite metropolitan exhibition. Early competing titles recognised that the skull crossed categories, even when they disagreed about the direction of the crossing. The work’s power lies partly in refusing to choose between extinction and persistence.

Stieglitz’s photographs and the public artist

In 1931 Alfred Stieglitz photographed O’Keeffe with a horse skull, producing images in which her hands, face and the bone create a carefully staged encounter. The National Gallery identifies the photographed skull with subjects used across several of her paintings and preserves one print as part of Stieglitz’s Key Set.[10][19] Photography brought artist and collected object together within the public image surrounding the new work.

The photographed horse skull is not the cow skull in CR 773, and the distinction matters. It nevertheless demonstrates how quickly skulls entered the couple’s shared visual economy: O’Keeffe painted them, Stieglitz photographed her handling one, and the gallery exhibited the resulting canvases. Personal collecting, artistic production and publicity were intertwined without making one medium a transparent explanation of the other.

The images could reinforce an idea of O’Keeffe as an elemental western figure, even though she still divided her life between New Mexico and New York. She did not settle permanently in New Mexico until 1949.[4][16] Reading the painting beside the photographs should therefore reveal deliberate identity-making, not retroactively turn the 1931 artist into the fully formed desert recluse familiar from later magazine profiles.

French scholarship has read O’Keeffe’s adoption of bone imagery as part of a desire for artistic and personal independence from Stieglitz, an interpretation strengthened by her increasingly autonomous New Mexican seasons.[21] It remains a historiographic proposal rather than a secret code embedded in the skull. The paintings and photographs show negotiation between two careers, while neither medium alone proves a simple story of liberation or control.

An American Place and the critics of 1931–32

The painting appeared in Georgia O’Keeffe: Recent Paintings, New Mexico, New York, Etc. at An American Place in 1931 and again in 33 New Paintings (New Mexico) during 1931–32.[2] A Stieglitz installation photograph documents it among other skull and regional works. The repeated display placed the emphatic national palette within a gallery sequence rather than allowing it to function only as a solitary emblem.

Contemporary critics responded through the language of trophies, life, death and transformation. McBride’s headline called the bones “grewsome trophies”, while McCausland paired skulls with roses.[2] Such responses demonstrate fascination and discomfort, but their sensational vocabulary should not be adopted as neutral description. O’Keeffe’s own interview answered the anticipated question—who would be bothered with bones?—by stressing beauty, sunlight and the desert.[3]

The gallery titles were themselves unstable. O’Keeffe’s American colour scheme, Stieglitz’s transformation labels and newspaper headlines each supplied a different route into the same canvas.[2] This documentary plurality warns against searching for one original verbal solution. The painted structure remained constant while the words around it made the skull patriotic, macabre, vital or metaphysical according to the needs of artist, dealer and critic.

From O’Keeffe to the Stieglitz Collection

O’Keeffe retained the painting from 1931 until 1952. By July 1949 it was on extended loan to the Metropolitan Museum as part of the Alfred Stieglitz Collection, and in 1952 she gave it to the museum within that collection.[2] The provenance contains no intervening private owner or commercial sale, making the work part of the body she deliberately placed in a major public institution after Stieglitz’s death.

The credit line can be misunderstood because “Alfred Stieglitz Collection” sounds like proof that Stieglitz owned the picture. Access O’Keeffe identifies the artist as owner through the gift date.[2] O’Keeffe assembled and distributed the collection in his memory, so the institutional name records commemoration and curatorial history rather than cancelling her ownership and agency.

The Met currently displays the work in Gallery 757, although gallery locations can change.[1] Its prominence has helped convert the image into a canonical sign of O’Keeffe and American modernism. That status is historical rather than automatic: it rests upon early exhibitions, O’Keeffe’s gift, museum publications, loans, educational programmes and countless reproductions that have made the frontal skull instantly recognisable.

Exhibition histories and changing Americas

After its An American Place debut, CR 773 appeared in a 1936 exhibition of new acquisitions from Abby Aldrich Rockefeller’s collection, longer displays of modern American and European art, O’Keeffe exhibitions and mid-century surveys.[2] Its inclusion in American Painting of the Depression Era in 1969 shifted attention towards the decade’s social and economic conditions, even though the painting offers no narrative scene of labour or hardship.

The 1970–71 O’Keeffe retrospective travelled from the Whitney Museum to Chicago and San Francisco, while Representations of America took the work to the Pushkin Museum, State Hermitage and Palace of Art in 1978–79.[2] An image originally framed as an internal argument about American painting thus entered Soviet-era international cultural display, where “America” could acquire meanings far beyond the artist’s 1931 provocation.

More recently, America after the Fall placed the painting within artists’ attempts to redefine modernism and national art during the Great Depression.[15] The 2016 Tate retrospective and the 2021 Centre Pompidou retrospective broadened international reassessment of O’Keeffe beyond flowers, stressing bones, New Mexican subjects, photographic framing and her sustained reinvention.[17][20] Each frame makes some aspects newly visible while leaving the object’s visual contradictions intact.

The object record establishes oil on canvas, exact dimensions, backing marks and current collection status, but it publishes no conservation narrative for CR 773.[1][2] Direct viewing of the authorised image reveals fine texture, soft blue transitions, opaque pale modelling and narrow tonal joins. It does not identify a commercial paint brand, pigment chemistry, ground composition, canvas weave or sequence of application.

The related CR 772 has an object-specific 2025 report describing pre-primed canvas, adjacent painted forms, exposed ground, an unvarnished surface and particular cracking.[6] None of those details should migrate automatically to CR 773. Comparison can generate questions about shared studio habits, but a technical statement requires examination of the actual canvas, especially because related works can differ in support, framing and later treatment.

The skull’s species is secure only at the broad level supplied by title and museum record: cow or bovine. No public source identifies breed, sex, age, ranch or precise findspot. Even the relationship between the painted skull and surviving bones associated with O’Keeffe remains undocumented. Visual exactitude should not be mistaken for scientific provenance; the canvas selects appearance without preserving a specimen label.

Correcting the inherited interpretation

The legacy page usefully notices bleaching, cracks, jagged edges, central alignment and the association of red, white and blue with the United States. It also recognises drought and modernist experiment as relevant contexts. Those subjects become more reliable when tied to the object record, O’Keeffe’s retrospective explanation, federal climate history, the 1931 skull series and the work’s documented exhibition reception.[1][2][11]

Several statements require correction. The backdrop appears fabric-like but is not documented as cloth; the skull is bovine rather than human; and the composition is neither conventional history painting nor a literal national flag. Most seriously, no evidence supports describing O’Keeffe as a staunch Christian who intended the image to affirm national Christianity. A cross-like reading is possible, but it must remain an interpretation grounded in form and related works.[5][14]

“Enduring American spirit” is best presented as one museum interpretation rather than the painting’s compulsory message.[1] O’Keeffe’s own story is sharper and more humorous: she used conspicuous colours to claim attention within arguments over a Great American art.[2] Keeping ambition, parody, beauty, death, drought and national symbolism in play preserves the work’s difficulty instead of converting it into a patriotic poster.

Looking slowly at an image built for notice

Begin at the outer red bands and move inward. Their unequal widths and painted edges establish a boundary before the blue field begins, while pale diagonal sweeps create the impression of folds or rays. Then follow the black central bar from the top edge towards the skull, noticing how it disappears behind bone and re-emerges through cavities until backdrop and anatomical darkness become hard to separate.

Trace the horns next, comparing their nearly horizontal reach with the descending central face. The intersection creates a cross-like scaffold, but close attention restores difference: horns taper organically, forehead plates crack, sockets are uneven and the nasal edges fray. Monumentality grows from the tension between strict central placement and the damaged, asymmetrical particulars of the actual skull.

Finally, test the title against what is visible. Red, white and blue are emphatic, but so are black, cream, grey and brown; the national colours are rearranged rather than obeyed. O’Keeffe made the image noticeable, exactly as she later said, yet notice is only the beginning.[2] The longer one looks, the less the painting behaves like a settled emblem and the more it becomes an argument about who can define American art.
