The four pieces to this set were all sold together. I have several wholesaler catalogs that show the set, which were made in the USA sometime well before 1920. The others in this set: a witch, a black cat and a girl running clutching a JOL all have a mechanical feature. This vampire clown, though, is an outlier relative to its design. Whereas the others are fairly tame designs, this one is wacky, odd and definitely a product of a fevered imagination. (It is almost as if the designer took something to prompt such an "out there" product.)
