Scarce original presskit celebrating the 50th anniversary of television.  A celebration and recreation of the events of the first broadcast was held in San Francisco on September 7, 1977.  Mrs. Farnsworth and their son Philo T. III were on hand.  This was promoting that event.  Contents include the printed folder, 7, 8 by 10 photographs with text, press release (2 copies), newspaper and magazine reprints, and an original newspaper clipping form 1976.  Scarce, I couldn't find another.  Combine to save on shipping.
