Cows, horses, antelopes and buffaloes are strewn across the scene in a powerful expressionist work which came early in the career of Pollock and was an important step in starting to gain exposure and respect for this artist.
Mural reminds many of some of the work produced by artist Wassily Kandinsky, who was a similarly expressive and highly creative artist from many decades earlier. There were enough influential artists for Pollock and others to draw on as they started to make their own way in the art scene.
