That is SOOO odd. It can't be a printing error though, maybe. It would have to have been cut off the card and then the card's borders wouldn't match the rest of the set. Actually, a printing error could be the issue. Since it only appears on Clark's card, maybe he was the corner card on sheets for the foil-printed version and the "FOIL 1" was an instruction. It just was put too far up and that put it on the actual card. I'd love to hear some more ideas about how this happened to that specific card.
