Museum Ludwig, located in Cologne, Germany, houses a collection of modern art. It includes works from Pop Art, Abstract and Surrealism, and has one of the largest Picasso collections in Europe. It holds many works by Andy Warhol and Roy Lichtenstein.

Roy Fox Lichtenstein was an American pop artist. During the 1960's, along with Andy Warhol, Jasper Johns, and James Rosenquist, he became a leading figure in the new art movement. His work defined the premise of pop art through parody. Inspired by the comic strip, Lichtenstein produced precise compositions that documented while they parodied, often in a tongue-in-cheek manner. His work was influenced by popular advertising and the comic book style. His artwork was considered to be "disruptive". He described pop art as "not 'American' painting but actually industrial painting". His paintings were exhibited at the Leo Castelli Gallery in New York City.
