This is a one of one printing plate of card #13, showing Herschel Walker, from the 2018 Panini National Treasures Collegiate set.
This is the Cyan version of the four plates available. Black, Yellow, Cyan and Magenta.
Two of the four, Magenta, and now Cyan, reside in the Herschel Hoard.
I'm very pleased to add this unique item to my collection.
