If you were wondering what the most wished-for radio of 1947 was, this was it, at least according to the manufacturer, the Automatic Radio Manufacturing Co., 122 Brookline Avenue, Boston.

The radio in question was the Tom Thumb portable, a four-tube (plus selenium rectifier) portable that came with its own rechargeable battery, undoubtedly a two-volt lead-acid cell. It could operate off battery, AC, or DC, and the battery could be charged internally (but now with the radio playing).

It was rather pricey, at $47, the equivalent of over $600 in 2022 dollars.

The ad appeared in the May 1947 issue of Radio Retailing.
