D.P. Carlson, the founder of Cinema Cellar, LLC, has been collecting posters since the 1970s, sourcing them from around the world.  He's also an independent filmmaker and lifelong cinephile, which gives him a good eye for what makes a poster worth having.

​

Over the years, that's turned into a collection covering the highlights of world cinema — not just posters from a film's home country, but the versions where the artwork hits just right.
