I think this card is from the All TIme Fans Favourite set from 2005, recreating a Topps 2000 card. However on TCDb, this card is numbered 113, whereas on the example I have it's numbered 2. (As can be seen in the scan)
I'm not sure where I got this card - I think it was in a "repack" of Padres cards. I know some of the other cards in those repacks had come out of factory sets, but I don't know if that's true of this one.
