Scott LevyThe same seller who recently auctioned off a honus wagner with red hindu back is now selling a Cobb / Cobb Back (on a green cobb with a black back).

This guy says that its being "sold as a reproduction though it doesn't show any signs of being one.".  I suppose that this technically protects him.  Perhaps I'm just a bit surprised what fakes like that wagner have sold for, although thankfully stew_p took that one down.  Am I just being too protective and need to let a few ignorant people find out the hard way?
