They would often sell posters from new or recent releases. They sold the posters shrink-wrapped to a piece of cardboard. There was a sticker on the outside of the packaging that claimed the poster was an "original" or "authentic" movie poster. Always single-sided I think. Size was usually a little off from the originals, but close. They were always close to 27 X 40.
Those Fight Club posters were one of the many titles they sold. I remember they had Star Wars Special Edition Struzan posters and Star Trek titles. Basically, titles that would appeal to their target male demographic. For example, I don't think they reprinted Pretty Woman, even though it was a popular movie. (If they did, I'm sure Cinemasterpieces has all the copies)
I think the Suncoast issue was something discussed on MPT back in the day.
Did I miss anything?
