Andy Warhol (1928-1987) was an American artist, film director, and producer who was a leading figure in the visual art movement known as pop art. His works explore the relationship between artistic expression, advertising, and celebrity culture that flourished by the 1960s, and span a variety of media, including painting, silkscreening, photography, film, and sculpture. Some of his best known works include the silkscreen paintings Campbell's Soup Cans (1962) and Marilyn Diptych (1962), the experimental films Empire (1964) and Chelsea Girls (1966), and the multimedia events known as the Exploding Plastic Inevitable (1966–67).
Warhol has been the subject of numerous retrospective exhibitions, books, and feature and documentary films. The Andy Warhol Museum in his native city of Pittsburgh, which holds an extensive permanent collection of art and archives, is the largest museum in the United States dedicated to a single artist. A 2009 article in The Economist described Warhol as the "bellwether of the art market". Many of his creations are very collectible and highly valuable. The highest price ever paid for a Warhol painting is $105 million for a 1963 serigraph titled Silver Car Crash (Double Disaster). His works include some of the most expensive paintings ever sold.
