This figure is a full-size Replica of "The Hatbox Ghost", a character that was featured for a brief time in Disneyland's Haunted Mansion. 

His head was intended to disappear from his neck and reappear in his hatbox . . . but it didn't quite work. He was quietly removed shortly after the attraction's opening, leaving only a few photos and memories as proof of his existence. More information can be found at Doombuggies.com.

I build a life size Bride figure to go with him, only for history to later reveal that The Hatbox Ghost was paired with a different version of The Bride that had nearly been lost to history.
