Original World War 2 business industry trade magazine vintage ad for THE DOW CHEMICAL COMPANY of Midland, MI.  Flight of planes always suggests the release of unfettered power.  No material used in aircraft construction has done more to free these essential weapons of war from hampering weight than magnesium.  Old 1943 WW2 era propaganda magazine advertisement.  Light stamp on the bottom page edge.  Would matte and frame beautifully.
