Which Georgia O'Keeffe painting features a cow's skull against a New Mexico landscape?

Cow's Skull: Red, White, and Blue features a cow's skull against a New Mexico landscape.

Georgia O'Keeffe painted Cow's Skull: Red, White, and Blue in 1931. The work places a weathered cow skull against a simplified background in the colors named by its title. It is one of her best-known paintings of bones and reflects her fascination with objects found in the New Mexico desert.

O'Keeffe collected animal bones and treated them as strong formal subjects rather than merely symbols of death. She emphasized their contours, openings, and pale surfaces, often setting them against broad skies or distant landscapes. Her bone paintings belong to the same broad New Mexico phase as her works featuring adobe buildings and desert terrain.

The title can be confused with other O'Keeffe paintings involving skulls, especially Ram's Head, White Hollyhock-Hills. The distinction is that this work specifically names a cow's skull and uses the patriotic color sequence red, white, and blue.
