The New York gallery known as 291 first exhibited Georgia O’Keeffe’s work. The gallery’s name came from its address at 291 Fifth Avenue in Manhattan.
Alfred Stieglitz ran 291, formally called the Little Galleries of the Photo-Secession. It became a major venue for European modernism and innovative American art. In 1916, Stieglitz presented O’Keeffe’s drawings there after Anita Pollitzer showed him photographs of them.
The gallery had closed by 1917, but Stieglitz continued exhibiting O’Keeffe through later spaces, including the Intimate Gallery and An American Place. The Armory Show was a separate 1913 exhibition, famous for introducing many European modernist works to American viewers. It was not the gallery where O’Keeffe made her exhibition debut.
