What Is This Frankenstein Head??

[Mutated Skeleton]

Does anyone know the origins of this Frankenstein's Monster Head? I bought this a few months ago at a toy show and the seller didn't know anything about it. Thanks for any help! I've tried google lensing this and haven't had any luck.

edit - I just realized there's a section for masks and busts, my apologies if this should have been posted there.

Yeah, I guess it's a bust, but, whatever.
