This set contains 15 cards (11 Doors and 4 Treasures) for Munchkin, drawn by Mike Krahulik the artist for the Penny Arcade webcomic, and designed by Steve Jackson the creator of Munchkin. The cards reference characters and situations from Penny Arcade and aren't very funny if you aren't familiar with the webcomic. The card mechanics, however, are different than the norm, so this set will add variety to any Munchkin game.
