A "roadshow" was a special 
        showing of a major film. Even though this type of presentation was around 
        since the silent era, David O. Selznick set the standard for the "roadshow" 
        presentation in 1939 with Gone With the Wind. It was called "showmanship."
        
        The criteria for a roadshow was:
       
        *A beautiful theater 
          *At least 100 miles apart 
          *Reserved seating
          *No popcorn, expensive candy bars
          *Courteous ushers and usherettes
      
      
        Here's a normal "roadshow" presentation.
          
          Upon entering, the audience was to see nothing but a huge curtain and 
          listen to parlor music, called an overture. The curtain was to open 
          to the studio logo, no trailers. The film was to be shown in a larger 
          format such as 65mm or 70mm instead of the normal 35mm. There would 
          be an intermission where the curtain would close. The audience was never 
          to see a blank screen. Music would start back up a few minutes before 
          the second half would start so everyone would know to take their seats. 
          Then, at the end of the film, the curtains would close and exit music 
          would be played. This was to give the atmosphere of an elegant presentation.
          
          Because these were special presentations on a larger format than normal, 
          the theaters were able to charge more than the normal admission fee. 
          Special advertising materials were created to show that these were not 
          the regular presentation. Roadshow advertising material quite often 
          was more beautiful than the normal posters. 
          
          The best way to identify "roadshow" material was to look for 
          special enlarged format logos on the posters, such as Todd-AO, 65mm 
          presentation, 70mm presentation, etc.

        six sheet for the 1963 blockbuster Cleopatra.

        Roadshow materials were issued in all of the standard sizes. They can 
        be either original release or re-issue, depending on the schedule of the 
        roadshow. When original materials were used, they would include a snipe 
        indicating "Limited Engagement," or other indication of roadshow 
        presentation.
