Sort through a wide range of images from movies, grace your door with the famous photo of Muhammad Ali standing triumphantly over his goateed evil doppelganger (20"x16", $6), or let John Wayne inspire your male guests to do bad John Wayne impressions as his rugged stare gazes out from the two-dimensional world of a 16"x12.5" tin sign ($18).
