FOUND BY JOHN WALKENBACH and also part of a musty collection of JFK Papers at home in Pennsylvania, this handheld "scrambler keeps private phone conversations safe from wiretappers and eavesdroppers. Fitted to an ordinary handset, it needs no electrical connection, has its own power source. To hear, a person needs an unscrambler coded identically. Delcon Division, Hewlett-Packard Co., Palo Alto, Calif., sells it for $275, keeps your name and code locked in its vault." The demonstrator is not ironing her face.
Modern Mechanix -- "Wiretap-proof telephone" from 1966.
