It was a part of the 1993 Topps Stadium Club Members Only multi-sport set. Here's a set description from the Mag Site.
"This 59-card standard-size set was mailed out to Stadium Club Members in four separate mailings. Each box contained several sports. The fronts have full-bleed color action player photos with the words "Members Only" printed in gold foil at the bottom along with the player's name and the Stadium Club logo. On a multi-colored background, the horizontal backs carry player information and a computer generated drawing of a baseball player. The cards are unnumbered and checklisted below alphabetically according to sport as follows: baseball (1-28), basketball (29-44), football (45-53), and hockey (54-59)."
