This is a RARE 1960s Star Trek 35mm half frame film clip originally purchased from Lincoln Enterprises.   This is a half frame film clip which is approximately 15/16 x 11/16 inches.   It is mounted in a 2x2 inch cardboard slide mount.  These film clips were discarded during the editing process and sold as individual frames to the public through the company Lincoln Enterprises.  These film clips have scratches and dust as these film frames were salvaged during the production and assembly of the Original Episodes.  These clips are mainly from dailies and workprint film the studio was going to discard, so this is a unique piece of Star Trek history.
