In order to create an early "buzz" around a new 
    film, many movie studios will issue what is known as an 'advance' poster. 
    These advertising materials are distributed to theatres and film distributors 
    well in advance of the film's projected release. 
  Advance posters are released in a variety of sizes and in 
    most countries, but it is normally in their most common sizes such as a one-sheet 
    or two-sheet, although other sizes were be used in a few promotions. 
  Depending on the films promotional plan, the advance sheet 
    may be identical or may differ significantly from the regular issue. 
  Some larger releases may have an initial advance released 
    with almost NO information about the film, including no credits and sometimes 
    may not even include the NAME of the film. These advances are called 'Teasers' 
    by older collectors. 
  In some cases, the studio may choose to put out a series 
    of advance sheets  each giving a little more information about a film. OR.. 
    a series of the major characters called 'Character Advances'. 
  In other cases, the artwork is identical to the regular issue 
    except that it will contain the projected release date. When it is part of 
    a series of advances, this is called the 'Final Advance'
  While there is no set standard for an advance one-sheet, 
    it will normally have one of these distinctions:
  
  On films with smaller budgets, only one poster is issued 
    which is used as both the advance and the regular.
