Cover ink credits first from Nick Caputo. Credits for pencils and inks from Julius Schwartz's editorial records provided by DC Comics, state that Irv Novick and Neal Adams were paid for the cover. Rob Hansen, via the GCD Error Tracker, points out that Novick's version of the cover, based on Carmine Infantino's layout, can be found in Carmine Infantino: Penciller, Publisher, Provocateur (TwoMorrows, 2010). Neal Adams alone did the pencils and inks for the published cover, though based on the same Infantino layout, as previously determined by art spotters for the GCD and indicated by www.nealadams.com.
