Haven't looked to see if any are listed but there were 8 different players taht had a 12-card set issued in 1991. Players were: R. Alomar, Bonds, Carter, Gooden, Griffey Jr., Justice, Sandberg, & Starwberry. All had a promo card issued prior anouncing the release date of the set. For Carter and Alomar, the promo card can also be found in a French version. Set print runs were 7,500 for the first 3 named players and 15,000 for the last 5.
