I have noticed, for this card set, the set link "Errors/Variations" is turned off. I have this card in my collection and on the reverse side, at the bottom, the football hosting the card number on my card is blank. I have examined it under scope and it is clearly missing. My internet search for another one has been unsuccessful. I can't possibly imagine my card being one of a kind. Has anyone else seen another or have one? I believe it should be considered as a error card, it has a error. Lol
