The Museum of the Weird
The Museum of the Weird has been a place spoken of only in rumors for decades, but it wasn’t until Maxwell Keep wrote of his family’s connection to and adventures in the depository of paranormal artifacts that we had any first-person account of its existence.
Disney imaginer Rolly Crump seems to have had knowledge of this unique and frightening place, as he drew various elements of it during the design phase of the Haunted Mansion attraction. Whether Crump had first-hand knowledge of the museum or he was just somehow incredibly intuitive and/or channeling information from another dimension is unknown.
You can see some of his drawings and concept pieces here: http://hauntedmansion.wikia.com/wiki/Museum_Of_The_Weird
There’s also a short comic series based on Maxwell’s account: https://www.amazon.com/Disney-Kingdoms-Seekers-Brandon-Seifert/dp/0785154523/ref=sr_1_1
