The past few years, one of the most challenging parts of completing a basic Topps Heritage master set (base set, short prints and the 3/4/5 primary insert sets) was completing the 15 card New Age Performers set. Well according to this checklist, the New Age Performers set is doubling in size to 30 cards this year! I have not had time to look completely over the entire checklist yet, but looks like the Real One Autos have some nice Hall of Famers like Bob Gibson, Frank Robinson, Stan Musial and Willie Mays. Plus there are mini cards this year! I will have to investigate this further tonight.
