This is the Red Back variation of the 2022 Panini Classics, #119 card of Herschel Walker. The cards are serial numbered to 99. The borders are white, which is why they appear washed out here.
Another in the Panini Mosiac line, this is a 2022 Mosiac No Huddle Blue card of Herschel Walker. Some call this the Disco version, due to the little bubbles on the card front. There is a No Huddle Pink, Gold, Silver, Purple and Black version as well. I have the Silver and Purple, the Black is a one of one. The above blue example is serial numbered to 75, this example being #74.
I was able to obtain one of the tougher Walker cards in the 2022 Panini Mosiac line. This is a Sparkle Gold, which is a Super Short Print card. There are short print cards, then super short print cards, which are even scarcer.
Panini is always cagey about how many of these cards are actually produced, but you can bet it is not many. Notice they are NOT serial numbered. The blue, red and white sparkle editions of this card are already in the Hoard, but those three are not SSPs. The only other one that is, would be the green edition, which I currently seek. You will always pay up for these cards on the secondary market.
