I just wanted to share one of my favorite theme park souvenirs in my collection. Sadly, I didn't purchase this new at Walt Disney World. I picked this up from a collector in the early to mid 1990s. I don't have a lot of history on the item, except that it is copyrighted Walt Disney Productions.
The top panel of the box says The Haunted Mansion in Walt Disney World Secret Panel Chest. It has several sliding panels that are designed to blend in with the box. It takes five moves to open the main box, then a sixth move to get to the second hidden compartment -- a small drawer.
Judging by the generic instruction sheet that was included, I would guess that these trick boxes were mass produced for other companies. Just the graphics on the top panel would have been altered.
