On emovieposter.com, Bruce has a DYK article on the E.T. The Extra-Terrestrial poster and how authenticate the release date of that poster based on the GAU and GCIU logos. If the GAU logo is present than the poster was release in 1982 and that the GCIU indicating a release in 1983. http://www.emovieposter.com/announcements.php?id=873What about a poster without either logo? I have a rolled poster with an NSS number but neither logo. Any idea about the release date on this poster?
Studio posters are printed either at the same time or before general release posters I believe. They are used mostly in the L.A. area to my understanding and are also sent to distributors and the like for pre-promotion
