All of the cards from football to baseball, Pokemon & Yu-GI-Oh came from same great local estate. The gentleman collected mostly Original Pokemon & Yugioh and had started on sports. This paper in pic was stuck in this box of cards. I’m assuming either these cards were to be in this lot, or supposed to be, or this is just an old paper? I did not look at one card nor do I have time. I’ll be selling all these cards as they come out of the totes.
