Roy Fox Lichtenstein ( 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 premise of pop art through parody. Inspired by the comic strip, Lichtenstein produced precise compositions that documented while they parodied, often in a tongue-in-cheek manner.

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. - Wikipedia
