What is the title of Georgia O'Keeffe's 1931 painting featuring a cow skull and an American flag-like color scheme?

Georgia O'Keeffe’s 1931 painting featuring a cow skull is titled Cow's Skull: Red, White, and Blue.

The painting places a weathered cow skull against a sharply divided red, white, and blue background. Its title identifies both the central object and the colors that give the composition an American association. O'Keeffe painted the work during the period when bones and desert forms became important subjects.

She collected bones during her travels in New Mexico and used them as formal subjects rather than merely as symbols of death. Their curves, openings, and worn surfaces offered shapes that could be enlarged and arranged with the same care she brought to flowers and architectural details.

The work is often discussed alongside O'Keeffe’s other bone paintings, including paintings of ram skulls and pelvic bones. Those related titles can cause confusion, but Cow's Skull: Red, White, and Blue is the specific 1931 work identified by its national-color palette.
