Don't be a sucker! Keep your mouth shut
Security poster: a large orange fish with a wide eye leaps toward a bare fishhook on a line, above the slogan 'Keep your mouth shut'. The word 'sucker' names both the fish and the person who talks. The sheet implies that careless talk gets a person caught, and calls the reader a 'sucker' if he does not comply.
