1990 Pro Set Joe Montana Error Card #2 Pristine Condition! Opened Pro Set Today!. This card is in pristine condition!! I just opened the Pro Set Pack tonight!(see pics) Card touched my hands one time …when I put the card in the hard case! It is the *Error Card* with the wrong ‘Jim Kelly Yards’. This is a great card for any collector out there because it has NO UNNECESSARY HANDLING!!(Like getting it graded) Don’t miss out on this opportunity, to own one of the all time error cards!!
