Pop art

Andy Warhol - Marilyn Monroe, 1962
Wikipedia - "Pop art is an art movement that emerged in the mid 1950s in Britain and in the late 1950s in the United States. Pop art challenged tradition by asserting that an artist's use of the mass-produced visual commodities of popular culture is contiguous with the perspective of fine art. Pop removes the material from its context and isolates the object, or combines it with other objects, for contemplation. The concept of pop art refers not as much to the art itself as to the attitudes that led to it."
