Georgia O'Keeffe's first major New York gallery exhibition venue was 291.
The gallery, formally called the Little Galleries of the Photo-Secession, occupied 291 Fifth Avenue in New York. Alfred Stieglitz directed it and later shortened its familiar name to 291.
Stieglitz began showing O'Keeffe's work there in 1916. The exhibition introduced her abstract drawings to the New York art world before she had met him in person. These works attracted attention because of their unusual lines, forms, and emotional intensity.
291 was important not only for O'Keeffe but also for American modernism. Stieglitz used it to exhibit European artists such as Picasso, Matisse, and Cézanne alongside American photographers and artists. The gallery closed in 1917.
