What 
            is a reprint?  
            A 
              reprint is a commercial reproduction of the movie art released at 
              the theater. Reprints are primarily divided into 2 major categories: 
              Commercial size reprints and theater size reprints. Even though 
              both sizes are still commercial reprints and therefore have no collectible 
              value, there is still a big difference in their handling and acceptance. 
              
            Commercial 
              size reprints
            A 
              commercial size reprint is a commercial 
               poster printed with the movie art image. These posters are 
              produced by the regular commercial printers that pay the royalties 
              to the studio to use the one sheet artwork. They normally measure 
              24"x36" or smaller and are sold through normal retail 
              and discount stores. 
            Theater 
              size reprints
            The 
              theater size reprints are a different story. These posters are normally 
              produced in Europe and shipped to the United States. They take a 
              larger printing press to produce the 27"x40" theater size. 
              Some are marked with the printers, like Zig Zag, across the bottom 
              to mark the reprint, but others have no reprint markings at all.
            To 
              non-collectors, these are GREAT! You can get theater size posters 
              for classic movies like Godfather, Jaws, Star Wars, 
              Breakfast at Tiffany’s and Casablanca that actually look 
              BETTER than the originals because: they don’t have fold lines; 
              they’re on a glossy paper; they don’t have the wear; AND they’re 
              at the GREAT reprint price. What more could you ask for!!!!!!
            To 
              a collector, as long as you’re dealing with movies before 1984 (these 
              were shipped folded) or posters that actually had a white border 
              (these were 27"x41"), is easy to tell the difference. 
              But newer releases are becoming so close that, more and more, these 
              are becoming a problem to the collectors’ world. With the increase 
              in printing technology, these theater size reprints are being printed 
              on the same quality paper, and are becoming harder to distinguish 
              from the originals. In the last few years, collectors have started 
              shifting to the light box posters double-sided 
              to help distinguish the difference. Some collectors base their whole 
              collections on them. NOW BEWARE, there is one printer that has started 
              printing double-sided reprints in Europe which will really become 
              a problem. Even though they haven’t been widely distributed YET, 
              because they’re a lot more expensive to print, expect to see these 
              collector’s nightmares raise their heads when there’s a major poster 
              that will make it worth while.
