This is a fan art which I did based on Wally Woods cover for Incredible Science Fiction.[link]
The original issue was published in 1955 the same year Marty went back to change his family's history.
So I thought, What the heck, lets redo a cover of a comic in that era. Although there is a fake EC comic in the movie which shows a flying saucer that looks a lot like the Delorean.
