Each full-color card in these boxed sets features a painting from the Perez-Steele Galleries of a great moment from the careers of baseball’s legendary players. On the backs of each is a detailed synopsis of the moment illustrated on the front, and the year of the Hall of Famers' inductions, as well as a checklist for the entire series. There are three complete sets included here and each has nine series, with 27 series total.
