Vintage Hancock 500 Brinell Valve Advertising Card 1944 Industrial Calendar. Vintage industrial advertising card promoting the Hancock “500 Brinell” valve, featuring a detailed illustration of the valve, bold mid-1940s typography, and a February 1944 calendar panel issued by the Hancock Valve Division of Manning, Maxwell & Moore, Inc., Bridgeport, Connecticut. The advertisement emphasizes extreme durability, near diamond hardness, and long service life for industrial steam, gas, water, and process fluid applications, making it a strong example of World War II era American manufacturing and engineering promotion. Printed on original cardstock with a plain reverse, the piece shows scattered age spots, light toning, minor surface wear, and gentle edge wear consistent with vintage industrial paper ephemera. An excellent collectible for those interested in valves, machinery, engineering history, Connecticut manufacturing, wartime industry, or mid-century commercial graphic design. P268
