I'm not too familiar with these, but I received packs of all the major card companies from National Trading Card Day. It would appear that each one contains a small sub-set with the National Trading Card Day logo on each card. If anyone is interested in any of these sets, then please let me know. I have the following sets: Topps, Donruss Classics, Playoff Prestige, Fleer, Upper Deck, and Press Pass. I can list who is represented in each set if you so desire.
