The 291 gallery gave Georgia O'Keeffe her first solo exhibition in New York in 1917.
The gallery was operated by photographer and art dealer Alfred Stieglitz at 291 Fifth Avenue in Manhattan. Stieglitz had first seen O'Keeffe's abstract charcoal drawings after they were sent to him without her permission by a friend, photographer Anita Pollitzer.
O'Keeffe's 1917 exhibition helped introduce her work to the New York art world. The show followed her years of teaching and study, including her experiments with abstraction after encountering the ideas of Arthur Wesley Dow.
The gallery is often called 291, after its street address, and was formally known as the Little Galleries of the Photo-Secession. It closed in 1917, the same year as O'Keeffe's first solo show there.
