Ya i see what youre saying. This is what i know about it
Did a quick opinion and it came back likely genuine
All the other signatures on it where members of the teams playing in that game.
If it was traced i think the person tracing it would put it in a better place and why would they sign it "Henry" and not Hank. Im 99% sure its good. Will send it to psa as soon as i get it. Never seen this type of program before.
