Hi every one.
Long time ago I went to a convention and got 5 original cast members to sign my poster. I really kick myself in the hiney for not getting more but that being said I also got Ken torrow to sign it. (I'm pretty sure I spelt his name wrong)
He wasn't in the film and only claims to have created the original mask.
My question is does his sig ruin the poster? Does it devalue it?
