Pop artists broke down the separation between fine art and popular culture in their work: Lichtenstein borrows the language of comics for his painting 'Whaam'. Pop art was associated to one of the key characteristics on Post-Modernism.
One of my teacher examples for a quick Lichtenstein Pop Art Portrait Lesson for the end of the school year. Handout has pre printed dots. They just draw, sharpie, and color.
