1951 RCA Fairfield ad on the radio
 

Hear this ad while I was doing some emailing. It can be hear if you go to http://www.archive.org/details/DuffysTavern
Then select the show dated the ninth of March 1951.
At 19:11 the ad start. That's if you don't want to listen to the whole show.
I have a Fairfield but I think the one in the ad is diagonal screen set, mine's a roundie from 1950
Enjoy
