Fibber McGee & Molly radio show 1/13/48 Fibber Invents the Cartable Radio

In this episode, McGee's latest get-rich quick scheme is inventing the "cartable radio", a cross between a car radio and a portable.
At that time, a radio was still a big piece of furniture in your living room, and some people had car radios. In about ten years, however, transistors came along and made portable electronics practical.
In all, a fun episode with all the humor and wordplay that made Fibber McGee and Molly a classic.
