This is a mint patch set of 6 that features the different department logos of Starfleet, first seen on the uniforms in the movie `Star Trek: The Motion Picture’. They were continued to be worn on the shirts in future movies, but were usually hidden by the maroon jackets. They include Command (silver), Science (orange), Engineering (red), Medical (green), Operations (yellow) and Security (blue). Originally produced by Lincoln Enterprises over 35 years ago, they have long been out of production. They measure 1.5″ x 2″, come with a glue backing for easy application to a cloth surface and are stored in a smoke and pet free environment.
