Roy Lichtenstein was an American artist known for his role in the Pop Art movement during the 1960s. He gained fame for his comic strip-inspired paintings, which featured bold colors and Ben-Day dots, a printing technique that mimicked the look of commercial printing. His work often included themes of romance, war, and consumerism, reflecting popular culture. Lichtenstein's most famous pieces include "Whaam!" and "Drowning Girl," which showcase his unique style and commentary on mass media. His art challenged traditional notions of fine art and helped to elevate comic art as a legitimate form of artistic expression.
