No offense but I have strong doubts this is real. In the first place, Reeves didn't play for the St. Louis Cardinals. He played for one of their "farm teams" - the Lynchburg, Virginia Cardinals. His performance for the farm team certainly wasn't impressive. I don't think he won a single game while he was with Lynchburg. I don't know if any companies even issued cards for semi-pro players. I think we would need to see the back of the card to determine if it was real or not.
