Color print advertisement for Dow Chemical Company. The advertisement highlights the use of Xanthates, a flotation reagent used for the separation and concentration of metal-bearing ores. An illustration shows a series of transparent bubbles; inside the bubbles are small illustrations of a plane, a tank, a ship, and a Jeep. The accompanying text describes the use of Xanthates in the production of "war-necessary metals" and refers to Dow Chemical as the largest producer of these flotation reagents. Notably, the advertisement was produced during World War II and bears the Company's wartime tagline "Dow: Chemicals Indispensable to Industry and Victory." This advertisement appeared in a 1943 edition of The Saturday Evening Post.
