I think it's a promo card... either from one of those 1 day card festival things where they give away cards, or it came with a LeBron toy? Eitherway, I've seen it sell on eBay between US$1-$3.
ok well im listing a few lebron cards on ebay and if you want this card it will be in the lot......i will list it in the lot as a promo card! have a look guys!
