Our three lines of national defense

Poster showing a battleship, an industrial cityscape, and military personnel behind an American flag. Title continues: The smoke of America's factory stacks is a signal of our workers' and employers' loyalty. It means more guns - more ships - more food. Our industries are the third and main supporting line of defense - our base of supplies. Without them the Army and Navy would be helpless. As good patriots let us strive to keep our industries strong. Poster showing a battleship, an industrial cityscape, and military personnel behind an American flag.
