The Studio Store: Featuring Monsters, Inc. & Muppet's merchandise, the Studio Store (formerly Rizzo's Prop & Pawn Shop) has an odd picture frame hidden on one of the store's walls. The Classic Hidden Mickey is made from three picture frames, with the larger center frame creating the head. It can be tough to find, but it is there - high up on one of the front corner support posts.
Note: Removed when the Studio Store was turned into Wandering Oaken's Trading Post
