Roy Lichtenstein became famous making large versions of comic book panels.
David Barsalou went to the trouble to discover who Roy Lichtenstein was copying.
wiki says :
Favoring the comic strip as his main inspiration, Lichtenstein produced hard-edged, precise compositions that documented while it parodied often in a tongue-in-cheek humorous manner. His work was heavily influenced by both popular advertising and the comic book style.
Frankly, some of his "precise compositions" were composed by someone else.
Lichtenstein didn't always make exact copies of the source drawings, but in my opinion, even when he did make copies he tended to make the drawings worse.
