I hope it's not a large deck of S&M containing four decks of S&M.
It could be anything; I'm going to go outside the box and guess it's a pair of D&D shoes.
Yes, a pair of fanning shoes! Hands tired? Wanna spice up the routine? Fan with your feet! Automatic fanning powder dispenser included!
What I really wish it is would be a free stripper jig, but that's just not gonna happen.
AIP is a reasonable guess - but kinda pedestrian. I'm thinking it's something more unique than that, and likely something no one has offered before. Remember, these are the guys who brought court-card coat hooks, hand lotion for card people and invisible bookshelves to the community... There's little reason to assume that this is a pack of cards or anything that closely related to cards, like a new clip, an AIP bottle, etc. Hell, it could even be a busker's vest! I've been dying to find a good one for a long time now.
