What was Georgia O'Keeffe's 1931 painting of a cow skull with national colors titled?

Georgia O'Keeffe's 1931 painting of a cow skull with national colors is titled Cow's Skull: Red, White, and Blue. The work combines a bleached animal bone with a blue ground and red-and-white stripes, creating an unmistakably American image.

O'Keeffe collected bones and other objects she found in the New Mexico landscape. She treated them as powerful formal subjects, using their curves and openings much as she used flowers and architectural details. The skull paintings also reflect her interest in objects shaped by weather and time.

This painting is often discussed as a symbolically charged work, but its exact meaning should not be reduced to one fixed interpretation. Its title identifies the colors and subject directly. It is different from O'Keeffe's related Ram's Head paintings and from her later Pelvis series.
