Looked for this card forever, never really knowing what to look for. Colla had quite a few different cards/sets back then, so I wasn't even sure which promo it could have been for. Luckily the seller showed the back to prove it was the promo. Will Clark,Mattingly, Canseco, Griffey, Sandburg, Strawberry, Justice, Gooden, Alomar, Bonds, Frank Thomas, Bagwell, or Ryan collectors have this? Or is Gwynn the only Promo?
