As covered before, there is a charity auction going on for the actual Screen-used Michael Myers mask worn by Brad Loree in Halloween:Resurrection! We are heading down the stretch here, as there is now less than 24 hours before the auction ends. All proceeds will be donated to charity as well.

What did this ultimately sell for?
Looks like $10,000
