Up for Buy Now is The Brute Michael Myers Mask from the movie Halloween 5: The Revenge of Michael Myers.  The mask was produced in vinyl  by Rudel Costume Company in Germany.  This mask was produced and purchased in 1989.  

I am the original owner and I purchased the mask from Hot Topic in 1989 shortly after Halloween 5 was released, hence it is from the origial production run.  The mask is in excellent condition and because it is made in vinyl it will never rot.
