As an addendum to the Topps Kirbyverse, I should mention that initially they bagged all their comics so they could include trading cards with their books. Many of them were by other artists, but Kirby art was used on the four card "Kirbychrome" set which imcluded the art from the covers of the solo books and part of the team centerfold from SATAN'S SIX, plus designs for SECRET CITY supporting characters like Cal Cutta, General Ordiz and Dreena and Brian Bluedragon of Satan's Six (inked by Dave Gibbons, Bill Sienkiewicz and others).
Also, oddly, their non-Kirby VLAD THE IMPALER series had cards which, when you took all nine from the three issues, formed this image on one side:
Which is, I dunno, one of Kirby's most enigmatic images, to be sure. I guess Dracula after an explosion or something? Anyway, inked by Mike Mignola.
