This classic 3-cent commemorative from the 1940 National Defense series symbolizes America’s industrial strength and democratic ideals. The central allegorical figure holds a banner reading “Equal Rights,” flanked by workers representing stock, mines, grain, and oil — key sectors of national prosperity. Printed in rich brown, the design reflects the patriotic, pre-WWII spirit of unity and productivity. A highly collectible example of early 20th-century U.S. socio-economic symbolism. Popular with thematic collectors of labor, industry, and Americana.
