An original Kodak Ektachrome Duplicating Film Transparency of a Ringling Brothers And Barnum Circus Poster that shows a grinning clown with a clear opening near the bottom of the poster. When making posters, the circus could fill it in with necessary information about the show, such a location and date in this opening. The poster was originally made in 1943. This is approx 8" x 10" and is in good, vintage condition with light wear.
