Megaphone Features “Mike” (Apr, 1939)

Megaphone Features “Mike”
OPERATED by batteries carried in a leather case slung over the shoulder by means of straps, as shown above, a new microphone-megaphone enables an announcer to speak in soft tones, yet have his voice heard by persons standing far away. Specially designed for use at stadiums and other places where crowds gather, the device has also proved valuable in helping policemen direct traffic.
