For many, classic Westerns, with their depiction of the spirit and struggles of the new American frontier, bring up feelings of nostalgia. Their stereotypical gunfights, tough sheriffs and rugged wilderness keep them popular — even though for contemporary film, the genre is now waning.

This exhibition, which explores how the Western helped redefine American film aesthetics, is the first in a series that covers world film history through billboard posters. The posters for this exhibition are mostly Japanese versions of the American originals, and include images of Gary Cooper, James Stewart and Clint Eastwood; till March 31.
