Unique Vintage Radio Flyer Wagon Silver Metal Lapel Pin from the World's Trade Show in Chicago in 1933. This was a salesman's sample and I actually confirmed the history of this pin with emails to the grandson and current CWO, of the Radio Flyer company and his title is "Chief Wagon Officer"! :-) This is such a rare item that I could not find another one online and was the basis of why I contacted him. I am not sure what the metal is, but it appears to me that perhaps it is pewter. It is very small, approximately 5/8", as shown in the first photo. The pin is attached to the wagon itself. It is very cool!
