This is a cool item with an interesting concept, but it is not a vintage piece. The two heads are patterned after two of a set of eight well-known fantasy lanterns that were first imported from Germany in the 1990s. The Germans did not celebrate Halloween until relatively recently, so everything made from pre-WWI through the 1960s was made for export. Nothing was kept, so when a dealer tells you that something was found in a warehouse in what was East Germany, or some such tall tale, simply laugh in their face and scuttle away.
