Arguably the horror genre's greatest 'scream queen' of all time, Jamie Lee Curtis made history last November when she appeared and signed autographs at Indiana's HorrorHound Weekend convention - the very first time she ever hit the convention circuit. Curtis vowed that it would not only be her first convention appearance but also her last, and that she would be donating all money made to Children's Hospital Los Angeles. Her experience at HorrorHound is documented in 'The Night She Came Home' - a special feature included on Anchor Bay's 35th Anniversary Blu-ray release of Halloween.
Though Curtis raised an impressive $150,000 for the charity, in just two days, her appearance at the convention inspired her to do even more. And so she rounded up five Michael Myers masks from her personal collection and proceeded to get them signed by as many living cast and crew members from the film as she possibly could - everyone from John Carpenter to Nick Castle, PJ Soles to Nancy Loomis. Though the mask isn't screen used, it's nevertheless got to be considered the Holy Grail of Halloween collectibles, considering the fact that most of the signatures (including Curtis') cannot be obtained on the convention circuit.
You can head over to Charitybuzz to check out the auction and place your bids. The auction will run through Halloween, and all proceeds again go directly to Children's Hospital Los Angeles. You'll also find a mask from Halloween H20 over there, which is screen worn, and is also loaded with signatures!
