The gallery that exhibited Georgia O'Keeffe's drawings in 1916 was 291. The name came from its address at 291 Fifth Avenue in New York City.
Alfred Stieglitz founded the gallery, originally known as the Little Galleries of the Photo-Secession, in 1905. It became widely known simply as 291 and presented photography alongside European and American modern art.
In 1916, Stieglitz showed a group of O'Keeffe's abstract charcoal drawings there after receiving them from her friend Anita Pollitzer. The exhibition helped establish O'Keeffe's reputation in New York before she moved there permanently.
The gallery closed in 1917, but its influence remained substantial. It introduced American audiences to artists including Pablo Picasso, Henri Matisse, and Paul Cézanne, while also giving O'Keeffe an important early platform.
