Oil on paper in the manner of Roy Lichtenstein "Marilyn Monroe", circa 1980, private collection, unframed dimensions are approximately 15x11. Roy Fox Lichtenstein (pronounced /?l?kt?n?sta?n/; October 27, 1923 – September 29, 1997) was an American pop artist. During the 1960s, along with Andy Warhol, Jasper Johns, and James Rosenquist among 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." His paintings were exhibited at the Leo Castelli Gallery in New York City.
