||Original linen backed World War II vintage poster. Tonnage built in American ship yards tripled after the U.S. entered the war. Poster shows a riveter using his wrench to bolt the steel plates of the hull of a ship together. Until the 1930s, when arc welding was introduced, bolts were secured by hand. Standardization speeded production. Make every minute count for Pershing.
