American Pop Art emerged in the early 1960s in response to post-WWII consumerism and mass marketing. Artists drew inspiration from popular culture like advertisements, comics, and movies to critique commercialism. Roy Lichtenstein and Andy Warhol were pioneering American Pop Artists. Lichtenstein created works featuring comic book speech bubbles and dots that referenced advertisements. Warhol produced famous paintings of mass produced objects like soup cans and portrayed himself as a celebrity artist.
