While Pro Line is well known as a pioneer of the parallel autographed set, we find no mention anywhere of there being factory signed versions of the National Convention set, so we are assuming the autographed was obtained after the fact. Signed in black without inscription, card is NM/MT. Card is from the set given away at a private party during the 1991 National, believed to be limited to approximately 250 sets. We guarantee all uncertified autographs to pass 3rd party authentication with CAS our authenticator of choice. If you want to get autographs certified you need to notify us before you pay. We submit them for you. If an autograph doesn't pass we refund both the purchase price AND the authentication fee.
