Roy Fox Lichtenstein (1923 – 1997) was an American pop artist. During the 1960s, along with Andy Warhol and others, he became a leading figure in the new art movement. His work defined the basic premise of pop art through parody. Favoring the comic strip as his main inspiration, Lichtenstein produced hard-edged, precise compositions that documented while it parodied often in a tongue-in-cheek manner. His work was heavily influenced by both popular advertising and the comic book style. He described pop art as “not ‘American’ painting but actually industrial painting. (wiki)
