Piece of flat die-cut plastic 2.25" across by 2.5" tall by about 3/16" thick. Reverse has small clear rectangle of plastic which in turn holds brass horizontal bar pin. Stylized depiction of the Fair's primary symbols including white line representing walkway that joined the Trylon & Perisphere plus at far left is a star apparently there simply to accent the design. The plastic the piece is made of is in dark green and the other colors are hand-painted. Unsual and Exc. Only example we've seen.
