The New York gallery 291 first exhibited Georgia O'Keeffe's work in 1916.
The gallery was founded and operated by Alfred Stieglitz at 291 Fifth Avenue in Manhattan, which supplied its famous name. It became an important venue for European modernism and for new American artists during the early twentieth century.
In 1916, Stieglitz exhibited a group of O'Keeffe's abstract charcoal drawings at 291. The show introduced her work to New York’s art world and began a professional relationship that shaped the public reception of her early career.
The gallery closed in 1917, after which Stieglitz continued presenting O'Keeffe's work through other spaces, including the Anderson Galleries and later his own galleries. 291 is sometimes confused with An American Place, the gallery Stieglitz opened later in 1930.
