The 1913-1915 T5 Pinkerton cabinet baseball set features an unknown number of cards, but appear with three different backs including scorecard, post card and blank backs. Each card displays a photograph of a player in action in black-and-white with the card number, his name, position, team and league printed within a rectangular box on the front. Each card measures 3-1/2” by 5-12”, give or take a quarter inch and provide no border. The most sought after examples feature the “Official Score Card” back with a grid lineup card. Desirable additions to this set include score card backed Hughie Jennings (#153), Ty Cobb (#159), Christy Mathewson (#251) and Honus Wagner (#872) and post card/blank backed Ty Cobb (#159), Christy Mathewson (#251) and Honus Wagner (#872).
