Original World War II U.S. War Department production poster titled “The Knockout Blow Starts Here — Fellow Soldiers.” Issued in 1942 by the War Department, Bureau of Public Relations, the poster links American factory production directly to battlefield victory. A series of black-and-white photographs shows workers manufacturing war matériel, alongside combat scenes, culminating in a graphic bomb-strike motif aimed at a swastika. UNT Digital Library
