Lon Chaney Sr's mask that he wore in THE PHANTOM OF THE OPERA, or his complete Red Death costume, along with the skull topped & snake staff that he walked down the opera staircase with, during the color Bal Masque sequence. 
Ohh, that's a great idea. I wonder whatever became of Lon Chaney's mask from Phantom.
I was thinking about the chandelier, but that's too big for my place.
I'd have to go with something I could easily slip into my pocket, like the heart of the ocean from "Titanic."
