Thanks so much for posting! Doing a bit of research in post-war research and technology and source material such as this is the ultimate!

I personally love the adverts from the 1940-50s that beckon entrepreneurial spirits to enroll in a radio or tv technician correspondence course. The copy is so similar in tone to modern day "Learn iOS" adverts from Flatiron School and the like: seize your destiny, build the future, get paid to do what you love, while changing the world.
