Now that is an awesome card! I love the oddball stuff because it is so much harder to find than the regular issue stuff. And unlike Topps from that year, they were able to use the Cowboy's logos.
Do you have any idea what this card books for? It seems when you come across these rarer, oddball items that the values are depressed because so many collectors hold these type issues in disdain. This kind of reminds me of the Carrolton Park Mall Cowboys set that I wished I had bought from the back of the Sporting News that we had spoken about recently.
