This should bring a smile to anyone who played around with radios back in the "good old days"...I received this today via email. It's a page from a 1960 issue of Electronics Illustrated showing a home-made, 4-tube transmitter/receiver project.
This is the "stuff" that we did as kids back in the mid-20th century and, amazingly, a simple set like this could communicate all over the world.

Pictured below is a 3-tube set that I made back in the mid-1960's. It had three tubes (6L6 transmitter, 6SN7 receiver and 5U4 power supply), and fit in the attache' case shown in the photo.
