LOT OF 2 1988 Baseball Card Kingdom Michael Jordan Promo Cards. #11 (Nike) UNNUMBERED (Slam Dunk Champion). In its heyday, Baseball Card Kingdom, which was located just beyond the gates of Disney's Magic Kingdom, was the world's largest baseball card shop. Since its closure, these amazing cards have been sitting in the attic of the owner (my supplier). These "one of a kind" cards were (back then) given away to customers. They have remained in incredible shape for 34 year old cards! The cards are standard baseball card size (2 1/2" x 3 1/2"). If you are looking for "unique" cards of hall of fame players, this is it! Don't miss your opportunity to own a part of trading card history!! All cards come securely packaged in a penny sleeve, semi rigid loader with liner and cardboard insert. AND FREE SHIPPING!!! Thanks for looking!
