The 2012 Bowman Platinum Hexagraph Book Cards contain a bunch of signatures on one card – six to be exact. There are only three cards in the set and with each card serially numbered to ten, you will have to shell out some serious cash to own one unless you are lucky enough to find one in a pack. Stars and soon-to-be stars in this set include Andrew McCutchen, Justin Verlander, Danny Hultzen, and Felix Hernandez.
