Keith de Lellis Gallery is a Manhattan gallery specializing in vintage twentieth-century photography, and occasionally nineteenth-century material, founded in 1997 after Keith de Lellis had worked as a private photography dealer since 1970. The gallery has occupied three locations on the Upper East Side and presents four to five exhibitions a year, free to the public, covering genres such as New York and urban photography, fashion, architectural photography, and photojournalism. Its program has featured both celebrated photographers, including Weegee, Margaret Bourke-White, and Edward Steichen, and historically overlooked figures, serving museums, collectors, and the public.
