Amazing enough.. 40" 
        x 60" posters measure 40" x 60" and are printed on a very heavy 
        card stock. They were primarily offered for major motion pictures only 
        and were displayed both inside and outside of theatres.
      40" x 60"s 
        normally feature the same artwork as the one-sheet. The  
        National Screen Service number is normally found on the side on the 
        poster, as opposed to the lower bottom as is the case with one-sheets. 
        40" x 60"s were normally shipped in rolled condition to the 
        theatre exchanges.
      Because of it's size 
        and being on heavy duty card stock, the 40x60 was used several times as 
        a standee. Additional re-enforcement was placed 
        on the back so it could be stood up in the lobby. For a sample of this,

      HISTORY 
      
40" x 60"'s were 
        first used as advertising materials in the 1930's for certain titles only. 
        Their heavy card material made them more durable than paper. They were 
        displayed in theatre lobbies, balconies, and bus, train and subway depots.
      40" x 60"'s were primarily 
        discontinued in 1984 with the collapse of the  NSS distribution 
        system. They are no longer used in todays movie market.
      AS A COLLECTIBLE 
        
      
40" x 60"s were 
        printed in smaller numbers than were other sizes of advertising materials. 
        Due to their beautiful artwork and their limited release, 40" x 60"s 
        are sought-after by some collectors that like the larger paper. Since 
        these materials were shipped to the exchanges in rolled condition, 40" 
        x 60"s lose some of their value if they are folded.
