The best I can guess is the second cards patch is in the card upside down and is part of the "ip" from
www.michaelwaltrip.com on the back of his firesuit. I have not been able to find good pictures of the firesuit really, and they change them so often, it is hard to tell. All the other 04 Hot Threads Gold of Waltrip, that I have seen, have the same section of letters on them.
