The listing is not only crazy - but misleading - When you read it, it sounds like he is kind of saying that this mask was in the movie...
All it is is a rare 1975 Kirk mask. Mask collectors might pay in the 10-15k range, but you can get a REAL screen used Meyers mask for 40k or so...
The only reason anyone even cares about this mask is because of the Halloween tie.. But the one for sale is just a rare mask - no connection to the film at all...
It has less connection to the actual halloween film than this guy has a connection to reality.
