American, 1923–1997. Roy Lichtenstein was a key figure in the Pop art movement. His early paintings were recreations of subjects borrowed from the works of his contemporaries; his artistic idols were Rembrandt, Daumier and Picasso. He would use their product as source material and would copy and trace it by hand, adjusting its composition to suit his goals. He referred to advertisements, comics, and everyday life for influence and was a pioneer in granting commercial art a respectable spot in the art galleries. His primary-color portrait of the cartoon character Mickey Mouse in “Look Mickey” (1961) brought him popularity for his deadpan style of humor as opposed to Abstract Expressionism reigning at that time.
