Georgia O'Keeffe's first major solo exhibition in New York was held at the 291 gallery in 1917.
The gallery was operated by Alfred Stieglitz at 291 Fifth Avenue and was formally known as the Little Galleries of the Photo-Secession. It had already become an important center for photography and modern art before O'Keeffe's work appeared there. Stieglitz first showed her drawings in 1916, then organized her first solo exhibition the following year.
The 1917 exhibition helped establish O'Keeffe in New York's avant-garde art world. Her works were mostly abstract charcoal drawings, made with sweeping lines and restrained compositions. The venue is often remembered simply as “291,” after its street number; it should not be confused with the 1913 Armory Show, a separate landmark exhibition that introduced many Americans to European modernism.
