Pretty random but I in 2002 on the paper pack numbers they had checklists on the back of them. They all varied as i believe each pack number had each version of the different checklists. I have got 19 of 20 pack numbers with the bulldogs on the back I am hoping someone in their collection has a pack 9 with the broncos/bulldogs/raiders on the back see picture. I have other pack 9 combinations I can trade for it so you wont have to be missing a card from your collection. I have other ones i can also trade if anyone else is doing the same. If anyone has one available it would be much appreciated.
