Inks credit in dispute.
DC credited the inks to Giordano in World's Finest Comics #302, Batman Illustrated by Neal Adams #1, Superman / Batman: The Greatest Stories Ever Told (story, not table of contents), Showcase Presents: World's Finest Volume 4, and Batman by Neal Adams Omnibus. Giordano credit supported by Joe and Victor (via the GCD Error Tracker), Tony Rose, and Gene Reed.
Adams inks per his current checklist and per Nick Caputo.
Giordano inks supported by his 1983 recollection (Green Lantern/Green Arrow #2) that Adams and he "had done a couple of World's Finest issues together for Mort Weisinger," apparently referring to stories in World's Finest #175 and #176. Giordano inks further supported by Michael Eury's 2003 index of Giordano's work in Dick Giordano: Changing Comics One Day at a Time (p. 161).
J'onn J'onzz has some powers no longer associated with him, including the ability to see the future, walk through walls, and affect the velocity of matter.
Script attributed by Rich Morrissey to Jack Miller. The current credit is from Showcase Presents: Martian Manhunter (DC, 2007 series) #1([July] 2007).
