...is that there are over 100 available Roush autographs on ebay this evening alone, with a few added every day. Not to sound too blunt here, but asking whether a Roush autograph is authentic is the baseball card equivalent of asking if a 1987 Topps card is a reprint. Are there reprints of 1987 Topps cards floating about? I'm sure there are. But is there really any reason to be concerned about it? It's a cheap and plentiful signature.
Here's a real nice one for 16 bucks. The seller has 2. Nobody is buying them for that price:

It would cost you twice as much as the value of the autograph to have it authenticated.
But I would pay big money for one on a Cracker Jack card, like the one I have on my website. Even though Roush signed just about everything known to man while he was alive, he appeared to sign precious few pre-war cards.
