Which New York City skyscraper did Georgia O'Keeffe paint repeatedly in the 1920s?

Georgia O'Keeffe repeatedly painted the Shelton Hotel in New York City during the 1920s.

O'Keeffe lived at the Shelton Hotel, now known as the New Yorker Hotel, after moving into the building in 1925. The skyscraper stood near Lexington Avenue and 49th Street in Manhattan and offered elevated views of the city.

Her paintings of the building and surrounding city emphasized geometric structures, vertical lines, nighttime light, and changing weather. Works such as Shelton with Sunspots, N.Y. and Radiator Building—Night, New York are often discussed in connection with her urban period.

The building is easy to confuse with the Chrysler Building, another famous New York skyscraper that appears in O'Keeffe's city imagery. However, the residence she painted repeatedly was the Shelton Hotel. Its later name, the New Yorker Hotel, can also create apparent differences in references.
