Radio dealers successful camera merchandisers The aggressive radio dealer has the necessary push to put over a bang-up job of camera merchandising according to F. G.

Action of every part of a radio transmitter will be illustrated by 6,400 flashing lights in various colors which wink on and off as different stages of the transmitter are activated.
