Usually not. Only because once word gets around ALOT of people ask for all the posters and it's just a headache to keep saying no and being bugged about it. Usually employees get them if they ask.
When I ran the projection booth I used to take alot of the standees and cut out certain parts and just put them all over upstairs in the projection booth. We probably have alot of stuff up there worth alot. The original Titanic standee, something about mary, original fellowship of the ring standee (which was awesome by the way) lots of pixar stuff, the best standee ever imho was for chicken run and it's upstairs mint condition. Most of the time they get thrown away, especially with the tripe hollywood has been putting out the past few years. There are special circumstances like for libraries asking for harry potter or one time a nurse at camp pendleton asked for the pearl harbor nurse poster to hang in the office, but for the most part the answer is no.
