Plagiarized artwork by Roy Lichtenstein
Middle image: As I Opened Fire (1966) by Roy Lichtenstein - the panel is an example of a 'Triptych' which is an art term to define a piece that is divided into three sections
Lower image: interior panel illustrated by Jerry Grandenetti and written by Robert Kanigher was swiped by pop culture artist Roy Lichtenstein without attribution
Lichtenstein also lifted the background art from a panel in 'Target Destroyed - Maybe' illustrated by Russ Heath for the painting, Okay, Hot Shot Okay! (1963)
Another panel in 'Target Destroyed - Maybe' was used in the painting Bratatat! (1963)
