Alfred Stieglitz's New York gallery 291 showed Georgia O'Keeffe's 1916 drawings.
The gallery was named for its address at 291 Fifth Avenue in Manhattan. Stieglitz founded it in 1905, originally as the Little Galleries of the Photo-Secession, before it became widely known by its street number.
291 exhibited photography alongside modern European and American art. Its program introduced New York audiences to important avant-garde artists and helped establish Stieglitz as a major promoter of modernism in the United States.
O'Keeffe's charcoal abstractions were shown there in 1916, although she did not personally meet Stieglitz until later. The gallery closed in 1917, and Stieglitz subsequently operated other spaces, including the Intimate Gallery and An American Place.
