Not sure if this is a Don Post or not because it's not marked. The people I bought it from in Boulder, Colorado actually claim it was in the movie which I cannot confirm. They bought it from a guy who said it was his dad's. An Ebayer wrote me advising it is and 80's Don Post mask but was never in a movie.
See close up of a little yellow partial sticker I don't know if that helps. It's old so it's certainly worth the Special Halloween pricing I have it priced at.
