THE RADIO BOYS SERIES
(Trademark Registered)
By ALLEN CHAPMAN
Author of the “Railroad Series,” Etc.
Individual Colored Wrappers. Illustrated.
Every Volume Complete in Itself.
A new series for boys giving full details of radio work; both in sending and receiving—telling how small and large amateur sets can be made and operated, and how some boys got a lot of fun and adventure out of what they did. Each volume from first to last is so thoroughly fascinating, so strictly up-to-date and accurate, we feel sure all lads will peruse them with great delight.
Each volume has a Foreword by Jack Binns, the well-known radio expert.
