Intercommunicating telephone with ten selector buttons, 1950
One of four intercommunicating office telephones, each with ten selector buttons, manufactured by ATM, c. 1950
One of four Bakelite office telephones for inter-office communication, manufactured by ATM. When combined with a wood flour filler, phenol formaldehyde, known by its trade name 'Bakelite' after its inventor Leo Baekeland, forms a useful mouldable plastic, with very good electrical insulating properties. It was the first plastic to be used for making radios, and was ideal for the Art Deco-style designs of the 1920s and 1930s.
