Absolutely spectacular and possibly one-of-a-kind original WWI/WWII era flag/banner for concrete shipbuilder, McCloskey. Due to strained resources on steel, the development of concrete ships was explored both during WWI and WWII. McCloskey was the larger manufacturer of concrete ships for the U.S. government, with their headquarters and facilities in Philadelphia, PA. Banner is stitched with graphics on both sides on heavy canvas. Banner has wear including staining and loose/missing stitching - particularly in the area of the ship graphic. Measures 7-1/2' x 4-1/2'.
