Roy Lichtenstein made a career copying comic book panels and selling them as pop art for millions. Now, one of his victims speaks out.

In this strip, veteran artist Russ Heath discuss his feelings toward Lichtenstein's Whaam! being based on one of his panels from DC Comics' All-American Men of War #89. Many of Lichtenstein's works were copied from comics, including works by legendary artists like Joe Kubert and Jack Kirby. Heath drew the piece in support of The Hero Initiative, a non-profit which gives support to comics professionals in need. The charity has helped figures such as ailing Rocket Raccoon creator Bill Mantlo, after a hit and run in 1992 left him requiring full-time medical care.
