Heyo, I'm one of the two people behind the Póstumo deck. I wanted to clarify that our original goal did not initially involve us printing with the USPC. While we had it available as an option, we first and foremost just wanted to make this deck of cards a reality.
Once we cracked the $10,000 mark, we had enough money for at least a minimum run on Bicycle-grade paper. Right now we're looking to hit $20,000 to afford two deck backs (plus the composite chips and Chessex dice costs).
And seriously, what the heck is up with the tchotchke obsession? We're trying to keep our rewards limited to the deck and things you'd actually use with the deck (although there is one reward level with a T-shirt on it).
