The Perils of Sharing Secrets During World War II
Quite arguably one of the most famous and effective propaganda posters, “Loose Lips Might Sink Ships” links sharing war secrets with the loss of American life and attacks on the Navy.

This slogan, created by the War Advertising Council, quite literally meant that citizens should avoid talking about ship movements, destinations and deployments because that information could easily be intercepted by the enemy at a grave cost.

This propaganda poster is a prime example of how a simple, clear and memorable slogan can convey the severity of an issue and influence public behavior.
