What was Georgia O'Keeffe's first solo exhibition venue in New York City?

Georgia O'Keeffe's first solo exhibition in New York City was held at the 291 gallery.

The exhibition opened in 1917 at 291, the avant-garde gallery operated by photographer and art promoter Alfred Stieglitz. It presented a group of O'Keeffe's drawings and made her work visible to an influential New York modernist audience.

The gallery was formally associated with Stieglitz's influential program of European and American modern art. He had already seen O'Keeffe's charcoal abstractions after a friend sent them to him without her permission, and he recognized their originality.

The 291 gallery closed in 1917, making O'Keeffe's exhibition part of its final period. Stieglitz later became her husband, but the exhibition is important independently because it established her public presence in New York.
