The New York gallery that exhibited Georgia O'Keeffe's work in 1916 was 291. Its name came from the gallery's address at 291 Fifth Avenue in Manhattan.
Alfred Stieglitz ran the gallery, which had originally been associated with the Camera Club of New York and became a significant center for modern art. It displayed photography alongside paintings, drawings, and sculpture, helping American audiences encounter European avant-garde movements.
O'Keeffe's presentation at 291 was significant because it introduced her abstract drawings to a powerful modernist network. The gallery closed in 1917, but Stieglitz continued to promote her work through later galleries. The number is easy to confuse with a gallery name or an exhibition title, yet it simply identifies the Fifth Avenue address.
