A simple image and a single word explode in Roy Lichtenstein’s heroic “Blam.” Originally painting old West scenes in modern styles, Lichtenstein (1923 – 1997) began transforming single scenes into paintings with a process that reproduced comic book-style dots. Lichtenstein’s cartoons, influenced by Cubism, poked fun at clichés, and were splashed with short sentences that he called Pop poetry.
