Adventure in Telezonia is a classic industrial film that was commissioned by the Bell System (today AT&T) in 1950 to help teach children how to use the telephone properly. The film features marionette work by Bil Baird, who had previously helped Bell make Party Lines, a 1946 industrial about proper telephone etiquette for the shared “party” telephone lines that were common in the rural United States in the early-to-mid 20th century.
