Antique Office Communications Equipment
Here's a cool spin on examining old communications technologies: Typically poeple look at interpersonal (letters, phones, telegraph, etc.) and mass media (radio, TV, film, etc.) as consumed by people in their private, domestic lives. The Early Office Museum has an exhibit of communication technologies used within the business sector. Not communication or media companies, but antique communications technologies used on the job, for both communicating within an office (telephones, call bells, speaking tubes, pneumatic tubes) and with outside parties (telegraph, telephone, teleautoprint, teletype, tickers, telegraphing typewriters, telegraphones and facsimile machines).
