The picture shows this 1939 - 1940 New York World's Fair Aviation Building Brass Badge / Pin. This badge has a great Art Deco design. It has images of buildings as well as the Fairs futuristic looking Aviation Building. It appears to be an employee pin rather than a souvenir. It measures 1-7/8" x 1-1/8". It is in excellent uncleaned condition with a nice patina.
