Mechanix Illustrated, Nov, 1941
EVERYBODY has at least one good invention up his sleeve—and now’s the time to cash in on yours!
Remember that idea you had last winter for a device to beat off air-raids? You always meant to get to work on it, but somehow never did. Or maybe you thought of a new kind of searchlight while working on your boat. Or a stunt which you believed would simplify minesweeping.
You’ve probably had ideas like these, or ones similar to them, at some time in your life and put them aside because you were ashamed to talk about them. Afraid your friends would ridicule you, or call you a nut.
