How did Roy Lichtenstein make his art?

Roy Lichtenstein made his art by using comic books and advertisements as sources. He took images from pop culture and then painted them using Magna acrylic paints that had a flat finish that mimicked the look of printing inks. The Pop artist worked mostly in primary colors and employed thick lines and Ben-Day dots to give his work a cartoon-like quality. Shop a selection of Roy Lichtenstein art on 1stDibs.
