I decided to take a break from all the 2022 Mosiacs I've been showing and post a very hard to find card of Herschel, which I just obtained.
This is a 2002 Donruss Gridiron Kings #160 of Herschel Walker, but what makes it special is the stamp on the card front. Originally, these cards could only be found at the 23rd annual Sports Collectors Convention, which was held in Chicago, Illinois, in March of 2002.
They were available for redemption only at the convention, now of course, they can be found on the secondary market. Although I've been collecting Walker cards for many years and this is the first time I've seen one come up for sale.
The cards are serial numbered to just five each. This example is #1 of 5. I should note that the cards have a very distinct white border, which is washed out in the background of this scan.
As always, I'm glad to fill in a long empty space in the Hoard.
