Among the best are
The 1st Star Wars movie, (+press sheet x2)
the 1st Star Trek movie
Superman 1 (Christopher Reeve)
All are standard poster size

I also have many posters from the 40s through to the 70s and 80s many with the original press sheets and half size posters

Most have been folded but are now stored flat (minor creases)

Also these are official ones, most double-sided, in good condition. I work at a movie theatre. LOL.

MOVIE POSTERS:

Watchmen
Star Trek
X-Men Origins: Wolverine
Terminator Salvation
District 9
Etc.

I want some movie posters (Star Trek, Twilight, Harry Potter etc) but, i wanted them full size so i can get them printed without having to go to the store and paying 5 bucks for them. are there any websites that have them?
