1963 Cubs Scorecard Signed by Roberto Clemente, Ernie Banks, & Others

This is a 1963 Chicago Cubs scorecard, Cubs vs Pirates. The scorecard is signed by Roberto Clemente, Ernie Banks, and other Cubs and Pirates. The game was scored by the owner, and Clemente hit a Grand Slam Home Run. The game was played on my birthday. Unfortunately the Cubs lost. This was found in an antique mall near Chicago. This sounds strange and unbelieveable,but as I was going through the door of the mall something told me I would find something today,(sometimes I just have a feeling), and it would be related to Roberto Clemente.Within 20 feet of the door there was a case with the program on the bottom shelf. The dealer did not know what he or she had. The price.......$24.00.
