Note: Comics listed were ones from which Lichtenstein derived inspirational material.
Comics were often used as the inspiration for Roy Lichtenstein's pop art pieces. He copied comic book artwork from Tony Abruzzo, Mike Sekowsky, John Romita and Myron Fass, among others. Among the genres which he copied, war comics and romance comics were among the most famous of his works.
There is some controversy surrounding the use of the art as Lichtenstein never gave credits to the original artist, and thus the original artist never received any royalties for their works being copied. Art historian David Barsalou has made a comprehensive list of comics from which the material may have been drawn (this is partially reflected in the list of issue appearances.) The list has some ambiguity, for instance in cases where Lichtenstein drew inspiration from comics panels of people kissing (a fairly common occurrence in romance comics.)
