Details: This poster is a war propaganda poster that shows a mouse trap that has sprung and caught a scrap of newspaper, which says 'Crew Claims U-Boat Knew of Ship's Sailing.' In the lower right corner are three small caricatures of Hideki Tojo, Adolf Hitler, and Benito Mussolini, who are referred to as 'the rats.' The text reads: Keep Your [Trap] Shut! Don't give the rats any information!
