I think that this one is really autographed, because it's the case that is autographed, not the card. So i think the guy ran into him at a race track and got an impromptu autograph, or he forgot his screw driver.
This one seems a little different than the other autograph, so i'm not sure if this one is really autographed.
If anyone knows, post a reply or message me. thanks
