www.xochico.com are the producers (since the 1800's) of the real Mexican loteria cards (which I love). click on "products" in tiny print on the left column, then "loteria cards and more" On the "what is loteria" page is an image of the hand card.
I used to be able to buy these sets at Wal Mart locally, but not now. I used them in all sorts of things. I wasn't alone- The Rubber Stamping craft industry has discovered them.
