Maybe i'm mistaken and mean no disrespect. But if you look at the third photo on the eBay listing, it is an order sheet for 100 US custom trading cards. You can go to the Topps website and order custom made cards with any name, picture, team logo and description. Thats what I was thinking these were.
Yes they are custom ordered cards from Topps, but look at the back of any custom ordered card from Topps then look at the back again at this card. Do you see something different about this card stock. These are not my cards by the way.
