This listener was all set for the summer of 1939 with the world’s smallest portable radio, the Majestic Model 130. The three-tube set weighed in at only 3-1/2 pounds, and measured a mere 7 by 5 by 3-1/2 inches.

Also shown are two other Majestic portables. The ad appeared 85 years ago this month in the June 1939 issue of Radio Retailing.
