Stock Photo - May 05, 1961 - The telephone of the future; This is the type of phone you may one day be using. Manufactured in Sweden, the phone combines transmitter, receiver, and dial in a single unit weighing less than the handset of an ordinary telephone. Here, Mrs. Sven Kallin, of Adelaide, Australia, shows the base of the phone in which is incorporated the dial and a rubber contact button. Contact is made when the unit is lifted up. The phone was one of the exhibits on display aboard the Swedish floating fair in the Kirribilli at Outer Harbour, Adelaide. (Credit Image: © Keystone Press Agency/Keystone USA via ZUMAPRESS.com)
