This is a little bit different release for this year. Normally, the Topps Heritage release features a single year from the past, and shows current players on cards from that design. Every year, the normal set design moves up one year, but this one is a bit different. It seems to be a one-off to just feature current players on 1951 Topps designs, in a box set format.

The box features
1 Full 104 card set
10 Mini Red Back Parallels
5 Mini Blue Back Parallels
3 Mini Green Back Parallels
2 Mini Black Back Parallels
1 Mini Gold Back Parallel
