The cover has been made up of images from the story it represents. It's swiped and redrawn from panels from "The Antique Collectors" story with new backgrounds by unknown British artist. Car Salesman figure from story page #2, panel #4, the lady figure from page #2, panel #3 and the man in hat is in a different pose (and different face) but clearly inspired by the one on page #1, panel #1.
