On this date 80 years ago, the November 7, 1942, issue of Radio Guide carried this ad for Motorola car radios. Production of civilian radios had ceased on April 22, 1942, but Motorola dealers still had prewar sets in stock.

We previously featured ideas for bringing the car radio inside. With gas being strictly rationed, the radio would do more good inside. But Motorola took another view: Since you had to drive slowly to conserve gas and rubber, the radio would make the slow drive more enjoyable.

But those prewar stocks wouldn’t last forever, so you were reminded to get yours before they were gone, because there would be no more for the duration.
