US careless talk text only poster warning people to watch out for and report any suspicious people or rumors co-produced with the FBI [Federal Bureau of Investigation] and the Office of War Information. It was part of the careless talk series of US propaganda posters distributed by the OWI, set in June 1942 to manage the war on the Home Front by disseminating ideas, propaganda, and information about the war, such as the dangers of enemy spies. The OWI controlled the design and distribution of war information to the American public in posters, photographs, radio shows, and films. The careless talk series originated in 1940 in Great Britain. It highlighted the many ways that careless talk could leak sensitive information that our enemies would use to kill soldiers, sink ships, and undermine the war effort.
