"Atomic"

Introducing for 1956! The Electrolux Electric Mail transmitter! Through the miracle of the new science of Digitalorium. You can now send messages to friends, and loved ones across the street, and around the corner.
Soon with the more advanced apparatus all the way across town!

Electrolux the first name in Vacuum Cleaners, and Electric Mail!

The above Electrolux Electric mail transmitter/receiver can be easily set up in your yard or roof. It's simple, and Tomorrowland stylish!

Caution. 

By order of the Atomic Energy Commission do not stand within 28.4 feet of or look directly at the unit when in operation. 

Enjoy being in close touch with friends no matter how many, (...line of sight), blocks away they may be.

(...So long as this does not exceed 2.8 city standard blocks.)

The coming Electric Mail Mark II,...ready for Christmas.
This will have a range of 3.2 miles!

Suddenly it's 1960 today!  All thanks to Electrolux!
