A card that's, well, it's not really a card.
This came in a pack of 2005 UD Mini Jersey Collection. These $7.00 packs had three cards and a mini-replica jersey.
The cards themselves were nothing special, but the mini jersey is pretty cool. And, in the only pack of this that I bought, I got Ken Griffey Jr.
The center part (not counting the sleeves) is about the size of a conventional card. The front
features little snaps. I suppose you could fit it on one of your G.I Joe action figures or something similar.
The question is, what do you do with something like this? It's not going to go into an album sleeve very easily. My solution was to mount it in a small frame and display it with my other non-baseball card baseball memorabilia.
As near as I can tell, Upper Deck only issued a baseball version of this set in 2005. But looking on eBay, it appears that Upper Deck is still publishing the hockey version. I looked through 5 pages of auctions and all the auctions were for hockey jerseys.
