Seeing as all the teaser trailers are on Eastman stock pre lpp, and are not rare, since many were made. Depends on what its worth to you.
I think 50 dollars for a trailer in pretty good condition is a fair price.
Not sure if any of the re-release trailers are LPP.
Cannot find out either because the last one posted was too much.
When they charge hundreds for a trailer it is pretty ridiculous. I saw a complete 35mm scope print for jedi unfaded LPP sell for 400 dollars about a decade ago on some film site.
Possibly stolen not sure where people get these things. He had the original jedi for that price but the 1997 special edition star wars for over 2 grand,lol.
The only auction i lost i really regret is the reel of Return of the Jedi in70mm that had the duel between Luke and Vader on the second death star.
Faded but not as severely as the empire prints i have seen. Except the warpage made the audio and picture out of sync so pretty useless except as a curio.
Scope trailers of the original release or any of the original 3 films prior to 1997 are hard to find though. Most trailers are flat and have a widescreen image reduced to fit the frame instead of the squeezed image.
Most illegal film cels from cut up prints are taken from trailers as well and not scope prints though some are.
The only licensed film cels i know of were the willets 70mm ones. Unless Lucasfilm licensed dealers to sale the 35mm cut up prints.
