The USPCC ended public access to their private collection back in 2001. I never had a chance to visit it. Was a catalog ever produced for this collection? I can only find Hargrave's 1930 "A History of Playing Cards..." as the closest thing to a catalog but it had no reference numbers to each deck.
I honestly don't know. I do know that, unfortunate as it sounds, I was told that the museum was basically "raided" by the company staff not long after the closing and that most of what was there, no longer is.
I do recall there was a museum that held an exhibit of USPC decks that was provided by the company, but for the life of me I can't remember which one it was. Maybe an exercise of your "Google Fu" skills will help you uncover it? That exhibit, at the least, might have a catalog.
