The picture shows a view of all (4) Old Hand Painted Monster Head GumBall Machine Pin Charms in this lot. These are not marked or dated but are believed to be from the 1960s. They were used as prizes in old gumball machines. Each has a brass pin on the back. They can be used as a pin or hung by the pin as a charm. They are all of the same plastic head but have slightly different hand painted markings. They each measure 7/8'' and are in mint condition as pictured.
