Make that 2 bogus Ty Cobb fans on ebay right now. This seller has a similiar strategy; the original owner says it real, one dealer says fake, one says real. And scroll down to see that, of course, "The seller will not accept returns for this item". All bases covered by the seller.
He even references the one Mark linked as an orignal selling for $7500. So you are really getting quite a bargain.
