This is the cover to Marvel Comics' Werewolf By Night #22:
The GCD listing credits John Romita with alterations on Werewolf's face.
Compare this image to the cover of Page Publications' Werewolf By Night #8:
As you can see there are distinct differences in some of the linework, prominently so on Atlas' eyes.
I'm guessing the Yaffa cover is a pre-production image which inadvertently leaked onto the Australian market. Or maybe the alterations are by Yaffa staffers. I'm not sure. If the pre-Romita art exists I'd love to see it to settle this query.
This issue was published late-1981 and reprints the main features from Werewolf By Night #'s 22-24. The splash page is omitted from this printing of Face of the Fiend.
