1854 Photo of Empress Eugénie dressed à la Marie Antoinette
Winterhalter took this picture while painting the preceding image. The San Francisco, California Museum of Modern Art ran an exhibition about the interaction of photography and art a few years ago and, if I remember correctly, this picture was part of the show.
