Movie posters. An excellent question. Just a few cherce things.
I *so* wish I had collected more in the 70s and 80s when I had the chances to do so all around me.
Psycho - original one-sheet
Rear Window - re-release one-sheet ("if your nerves can take it after seeing Psycho")
Torn Curtain - half-sheet in only fair condition
The Haunting - original (what's the vertical 14"x36" called? insert?)
The Exorcist - original one-sheet
Mr. Sardonicus - original one-sheet in only fair condition
La vallée des poupées (Valley of the Dolls) - original French three-sheet (thank you, BK and Indiegogo)
Rear Window - #1 original lobby card signed by Hitchcock (no caricature, it was scribbled in a hurry)
Quite a few other lobby cards (many Hitch, a few signed by actors) and some B&W & color 8x10s from various movies.
Various and sundry odds and ends, and no doubt a few things put away that I'm not thinking of.
