Here are a few more examples of Kirby from What If? # 11 (1978). There are so many good ones to choose from, but I don't want to violate Marvel's copyright and incur the wrath of their lawyers, so I'll limit myself to 5 examples. If you are a fan of Kirby and 60s Marvel comics, definitely pick up a used copy of this book on eBay. Jack wrote it and illustrated it with inks by Royer and Bill Wray. It's a fun, visually stunning romp through the mythos of the Bullpen and Jack's Fantastic Four. Technically this is also the last time Jack draws a full book featuring his Fantastic Four characters, and at 34 pages this one packs a wallop.
