I see the similarities. As you're probably very aware, there are 2 nice illustrated versions of that Bradbury story, one by Al Williamson(WEIRD SCIENCE FANTASY 25, Sept 1954), and one by Richard Corben.
Both the Williamson and Corben versions are published in
RAY BRADBURY COMICS 1.
But Wrightson said it was actually a parody of a series of Arrow Collar Shirts magazine ads running at the time.
The full title of Wrightson's picture is "Gentlemen of Adventure wear Arrow Collar shirts"
