They had Wes Unseld in some of those 2008 products as well:
I've always assumed it was the same prime relic they used for him later on in NBA products. However, it says it's player-worn on the back. It's one of the few instances I've seen of a retired player having player-worn relics in basketball during the Panini era. I wonder why they labeled it that way and said the Wilkins was game-worn? Weird.
