Back in 1992 the Mother's Cookies produced several sets of team cards. A's, Astros, Dodgers, Giants, Mariners, Padres, and Rangers, as well as small sets of Jeff Bagwell, Chuck Knoblauch, and Nolan Ryan.
This particular card came to me from Greg at Night Owl Cards. He recently whined commented on wanting to see Mr. Hershiser in a Dodger uniform. Here you go, Greg.
