"On the Air," an NBC Radio Promo Comic from 1947.
Jimmy’s little sister had it right when she exclaimed as they listened to an elaborate radio dramatization, “It must take an awful lot of work and — and people to put on a show like that!”. Jimmy himself remained unimpressed until he was reduced drastically in size by a manic and frightening anthropomorphous microphone and shown just how complicated and expensive the whole process really was.
Although this 16-page giveaway comic book put out by the National Broadcasting Company in 1947 is mainly a puff piece hyping all of the amazing material that one could dial up for free at home on their radios, it also stands as a fairly accurate guide to NBC procedures at that time. Still, that evil little microphone character is just scary; no way around that. We even get a glimpse of the early television broadcasting setup from New York.
