This is a 1992 Wild Card Field Force Gold 20 Stripe card of Herschel Walker. These Wild Card striped versions are very tough to find, especially in the Field Force or Running Wild subsets.
What differentiates the Gold version from the regular is the gold flecking in the left hand border. Sometimes it's tough to see in a scan, but with the card in hand, it's easier to see.
The "20" is shown in the diagonal black band on the lower left of the card front. Again, it is kind of tough to see in the scan.
I'm extremely happy to add this card to the Herschel Hoard.
