Exclusive Warehouse 23 Munchkin Booster

The Exclusive Warehouse 23 Munchkin Booster is pretty much described by the name: a fixed set of cards for the various Munchkin games sold exclusively through publisher Steve Jackson Games' retail outlet, a.k.a. Warehouse 23. A booster was released annually between 2010 and 2014, and in 2016 Steve Jackson Games re-released all of the standard-sized Munchkin cards from those boosters as Munchkin Hidden Treasures.
