United States, 1939
Say it's 1940 and you're out for a Sunday drive. You want to fire up that newfangled radio thingamabob and find some Benny Goodman. But where, oh where to turn the dial? You wouldn't be so lost if you had one of these handy RCA Radio Tour maps, distributed by RCA radio dealers and perhaps in magazine ads. The map urges you to explore the 650 AM stations on the air at the time. "Don't be satisfied with nearby stations -- reach out for your radio enjoyment," it says. "Be a radio tourist."
