Most
producers of special distribution movies release advertising materials
to go along with their films. Just as these movies are targeted
for "special interest" groups, their movie posters are also sought-after
by 'special collectors who prefer collecting the materials on these
limited distribution films.
The
advertising materials for these types of "special target audience"
films do not share the same widespread acceptance mainstream movie
materials. However, because of their smaller distribution, there
are limited numbers available thus making them harder to obtain.
Posters from X-rated films, independent films and war documentaries
are particularly popular with some collectors.
