I don't know how rare they are, but some of the one-sheets I own don't seem to pop up too often anymore, then again I haven't bought any posters for a long time: House By The Cemetery (US), Gates of Hell (US), Don't Look In the Basement, Last House On the Left 1972 original, The Burning, Hands of the Ripper, Devil's Nightmare, and Midnight just to name a few. I have a red plastic straw and on the wrapper it has Bloodsucking Freaks available from Vestron Video. It was thrown in a video order along with some other promo stuff I received back in the 80s. Is that kind of stuff collectible?
The straw is definitely collectible, and likely deeply scarce; I have an icepick that the video company that released "Frozen Terror" (Bava's "Macabro") sent to video stores. "Pick a winner" is the slogan that's printed on it. At no time, however, have I used it to dig out snot.
I wish I knew how rare (or not) the ones I have are...maybe one of you guys could let me know if any of these are hard to find, as I haven't picked up any posters in quite some time. I have originals of: The Burning, Madman (my personal favorite), Halloween 2, 3,5 and 6, Friday the 13th 3 and 6, Silent Night Deadly Night and finally Xtro of all things.
There is one of these on ebay right now if anyone is interested. http://cgi.ebay.com/Friday-The-13th...emQQptZLH_DefaultDomain_0?hash=item518da6090d
I don't have many posters, so my rarest is easily the Predator 2 "Hunting Season" double-sided light box one. Pretty sure everything else I have are re-prints or cheap home ones, this is my only real theater poster.
My rarest poster would probably be this banner from the original Thing 1951. It's approximately 2' x 8'.
Oh where do I start. I have original posters for all Argento films, italian, german and french ones till Suspiria. Also US poster of Suspiria and italians for all his subsequent films. Les Amants of Louis Malle (italian poster). Husbands / Opening Night (Cassavetes), french posters Lemonade Joe , US poster Panic in Needle Part, US poster Fingers (Toback), italian poster and a 100 more I cannot for the life of me unearth just to answer this.
I collect original Insert posters, I have from memory, Jaws Mr Majestyk The Mechanic The Dead Zone Dead & Buried The Burning Star Wars The Empire Strikes Back The Return Of The Jedi First Blood Omen II Magic Rolling Thunder Race With The Devil Close Encounters Of The Third Kind They look great framed
For me it has to be my Night of the Zombies American 1-sheet. I spent the better part of a year, trolling around ebay for that one. Other good ones include: The Burning Shockwaves Mausoleum Deathship Revenge of the Dead Pieces Maniac
I have several dozen theatrical posters I've accumulated over the years, both horror films and Disney animation (I primarily collect vintage Disney stuff)....My most prized overall is an original 1951 Alice in Wonderland one-sheet....Beyond that, my faves are (not sure how RARE): 1963 Black Sabbath (American release) 1965 Planet of the Vampires (not sure of year, but it's the original AIP release) 197? Horrible House on the Hill (alternate title for Devil Times Five, which has artwork of woman with fishbites all over her, and says "If Shower Scene in Psycho scared you, wait until Susan steps into the tub") and a lovely art deco-y 1974 Noche De Los Brujos (Night of the Sorcerers) I also have a nice 1970's rerelease for Sleeping Beauty, that has really beautiful color swirls against a black background...
I also have: Friday the 13th Part 2 (Aussie 1 Sheet) Just Before Dawn Final Exam Fall Break (Mutilator original Title)
Years ago, I picked up an original theater poster for the Joe Don Baker movie Mitchell, which later became famous as an MST3K episode. The poster itself is a heavy cardstock type paper and has a few pinholes and minor stains which I like to believe is spilled Schlitz. My poster is in much better condition than the image below...
As for rare, I've got video store posters for: Night Life Prom Night III: The Last Kiss Prom Night IV: Deliver Us From Evil The Paperboy Rush Week Berserker I doubt they're rare because they're in high demand, just because they weren't really BIG movies. Plus I have a few that were already mentioned, like autographed The Mutilator and Fall Break, 2x sided Jason Goes To Hell, etc.
