Ryan Sook Superman

As I understand this, Jon Bogdanove laid out or pencilled this drawing and Ryan Sook inked the piece. Unfortunately, Bogdanove did not sign it. Funny how that works. I have several Magic Man and Nemesis covers I know are Schaffenberger, but they were signed by Pete Costanza (since Schaffenberger had an exclusive contract with DC at the time), People tell me I'm nuts when I say they are by Schaffenberger. "Look who signed it", I'm told. But it looks nothing like Costanza... at all. It is all Schaffenberger. Anyway... using that logic this is just Sook.
