New member who has always been a fan of the original Exorcist film, and also a collector of rare stuff. I will admit to having purchased from Royal Books in the past, but I don't represent them. Reason I bring 'em up, though, is they've got a nice little treasure trove for those who want to see what went into the film.
I wish I could plonk down the money for this. Still good to have this digital image, at the very least. Great find, father_k, and welcome to the forums.
