In honor of the 35th anniversary of Halloween, Jamie Lee Curtis has partnered with global charity auction site Charitybuzz to auction off Michael Meyers masks from her personal collection! The scream queen has generously donated a replica of the mask from the original 1978 film, one of five in her private collection, with signatures from the surviving original cast members (pictured); John Carpenter, Nancy Loomis, Kyle Richards, and more; making this an incredibly rare item for any memorabilia collector!!

There is also a film-used mask from H2O: Halloween 20 Years Later up for grabs, featuring signatures from Michelle Williams, LL Cool J, Joseph Gordon Levitt, Josh Hartnett, and more.
