Now this was where technology was headed in the the 1960's. This chunky phone device would scramble the signal so eavesdroppers and wiretappers couldn't hear your conversations.
It cost $275 back in 1966 and that was lots of money back then.
I've never seen these before, have you? Looks to me like the beginning of the cell phone age.
How far we've come!
