Dominoes on the back, of course. So you can play dominoes, I guess. The set is 129 cards, but each allegedly has three color choices and all the domino pairs, so good luck if you're a completist. As for Art Fromme, he played 10 years in the majors, half with Cincy, half with the Cardinals and Giants, winning 80 games. This is my second card of his, the first being a T206.
