Possible Verpoorten and Abel credits per Nick Caputo, Sept 2011, who adds: "I recently saw a large size scan of this cover on whatifKirby and the cover is a patchwork of pasted-up and repositioned art. The Hulk face looks like its inked by Verpoorten; Groot, Goom and Blip appear to be by Kirby, although I'm uncertain if Verpoorten inked these figures. Xemnu looks like Kirby, but his arms appear repositioned by Romita. Diablo and Taboo are either greatly revised from Kirby's pencils or added by Romita, with possible inking by Abel."
