Which New York building did Georgia O'Keeffe paint in her series beginning in 1925?

Georgia O'Keeffe painted the Shelton Hotel in a series that began in 1925.

The Shelton Hotel, now known as the New Yorker Hotel? No—the building associated with O'Keeffe's series was the Shelton Hotel, later called the Shelton Hall Hotel, at 525 Lexington Avenue in Manhattan. O'Keeffe lived nearby and used views from high floors to explore the geometry of New York's architecture, streets, and winter light.

Her urban paintings from this period helped broaden her reputation beyond flower imagery. Works such as Shelton with Sunspots, N.Y. and Radiator Building—Night, New York show how she translated skyscrapers and artificial illumination into modernist compositions. The city became an organized field of verticals, diagonals, shadows, and glowing color.

The building is sometimes confused with other New York landmarks that O'Keeffe depicted or that appear in accounts of modernist New York. The specific hotel in this series was the Shelton, a residential skyscraper on Lexington Avenue.
