This issue has variants.
Oddly, this version has an entirely separate barcode on the back cover with a second upc number. The back cover, including the upc box, is identical to the back cover of the Quesada variant.
The cover is an homage to the cover of Giant Size X-Men (Marvel, 1975 series) #1.
Since the story inside does not include the official Marvel Zombies, this should not be considered a Marvel Zombies appearance.
