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.
