Which 1931 Georgia O'Keeffe painting features a steer skull and an American flag?

Cow's Skull: Red, White, and Blue is Georgia O'Keeffe's 1931 painting featuring a steer skull and an American flag.

The painting places a large bleached cow skull against a blue background, with red and white bands behind it. O'Keeffe found animal bones in the New Mexico landscape and repeatedly used them as monumental subjects rather than treating them as incidental remains.

Its patriotic colors connect the skull to American identity, while the stark composition turns a found Southwestern object into an emblematic image. The work is often discussed alongside O'Keeffe's other bone paintings of the early 1930s.

It should not be confused with Ram's Head, White Hollyhock—Hills, another famous work combining a bone with a New Mexico landscape. The skull and the ram's head are different subjects.
