his mint patch pictures the command logo of Starfleet, on the security version. This blue patch was first seen on the uniforms in the movie `Star Trek: The Motion Picture’. It continued to be worn on the shirts in future movies, but was usually hidden by the maroon jackets. Produced by Lincoln Enterprises over 20 years ago, it has long been out of production. It measures 1.5″ x 2″ and it has a glue backing for easy application to hats, shirts, jackets and bags and is stored in a smoke and pet free environment.
