If you went to 10 different booths at comic-con this year and recieved a stamp at each and returned to Cartoon Network's booth you recieved this awesome Adventure Time Medal. This by far is one of the coolest swag quests from Comic-Con ever and well worth it for such a great prize. Well done, whatever PR Team came up with this one. If you want one, they are going for $20 and up on eBay.
The stamps and map. So your treasure map of Ooo flipped over for stamps to get.
