This iconic dress is called "The Souper Dress." It was made in 1966-1967. It was inspired by pop art. "Pop art featured glorified representations of ordinary objects such as soda cans and cartoon figures."
For the first time, 300 drawings from the 1950s are on view at the Louisiana Museum of Modern Art in Denmark. The previously unreleased collection of works are loan by German gallery owner Daniel Blau, who obtained the works from the Andy Warhol Foundation for the Visual Arts.
