Which Manhattan skyscraper inspired Georgia O'Keeffe's Radiator Building paintings?

The American Radiator Building inspired Georgia O'Keeffe's Radiator Building paintings. The Manhattan skyscraper, now known as the American Standard Building, stood out for its dark facade and bright ornamental details.

O'Keeffe painted New York architecture during the 1920s, when the city’s vertical scale and new skyscrapers fascinated artists. Her 1927 painting Radiator Building—Night transformed the building into a dramatic arrangement of dark geometric masses and glowing red-orange forms.

The building was designed by Raymond Hood and André Fouilhoux and completed in 1924. It was created for the American Radiator Company. O'Keeffe’s painting is not a depiction of the Chrysler or Empire State Building, although those landmarks belong to the same era of New York skyscraper culture.
