"On a great planet whirling somewhere in space a strange war is being waged. It is a war in which insects are fighting against men. Incredible as it may seem, the insect foes are pressing the human armies very hard." This planet of course is the earth and the Copper and Brass Research Association recommends protecting your family from insect-borne peril by investing in copper or brass insect window screens. The illustration styles would suggest Jazz Age screens.
