Available for sale is a hand autographed Wilt Chamberlain card that I personally obtained back in the 1990's. This has a bold, clear signature(with a Sharpie) on the front of his 1974-75 Topps card. This item is guaranteed authentic as I was the one who handed the card to Wilt at a restaurant that he owned in Florida at the time. Chamberlain was perhaps the most dominate player in the history of the NBA and rarely signed even when he was still alive.
