In continuing with the 2018 Panini Contenders set, here is a card with a bit of a different look. It is from the Old School Colors series. Herschel's card number for this series is 12, where as it had been #50 for the other cards in the set.
This is one of three possible "gets" of Walker in this particular series. There is also an Old School Cracked Ice version, which is serial numbered to 23; and an Old School Championship version, which is a 1 of 1.
