Incredible Hulk #100 Gray (Grey) retail incentive variant comic book from Marvel Comics. Retailers had to buy 50 copies of the normal issue to get just one of these! This double size commemorative issue features a great Michael Turner (Fathom, Soulfire, Witchblade) cover with the grey Hulk rather than the green one! A super Near Mint copy of this highly collectible rare variant comic book.
