The wonders of Electricity!  What did folks foresee in 1919?  Radio direction finders!  Dental x-Rays!  Electric light baths!  Electric washing machines -- with a motor-driven wringer!  Electric stove!  Electric cooking utensils!  Vacuum cleaners!  Even, if you can believe it, a dish-washing machine! 

No wonder the great age of Science Fiction was about to dawn!  This was the Future, man, an electric thrill in store for everyone!  Hoo-ah!

I especially like the demure young Lady Electricity, emblematic of a less provocative age of clothing.
