Found this while looking for a mannequin head to display a Frankenstein mask. I think it would make a great head for a life size Captain Picard/Professor X. I believe it may actually be a Patrick Stewart bust and not just a generic mannequin head so the seller apparently doesn't know what he has. Then again for an opening bid of $85 maybe he does know what it really is but I don't know why he wouldn't list it under a more suitable category. Looking thru his feedback history he has sold a few others of these as well as a mannequin head that resembles Jim Carrey
