Orig 1939 NYWF New York World's Fair Enamel Pin on Card

It's always a plus to find an old souvenir on its original card. This chrome and enamel pin came from the 1939 NEW YORK WORLD'S FAIR. The pin features the Trylon and Perisphere in orange and blue...the Fair colors. Card measures 2 1/2 by 3 inches. Pin measures 3/4 inches across. It shows some age corrosion at edge. Some age soil to card but overall, this vintage Fair item is in great original condition.
