Loose Lips Sink Ships

During the Second World War, Americans were repeatedly warned that careless conversation could reveal troop movements, ship sailings, or other information useful to the enemy. Among the best-known reminders was “Loose Lips Might Sink Ships,” a 1942 poster that became part of the wider wartime campaign against careless talk. The phrase quickly outgrew the poster itself, becoming one of the most enduring expressions of home-front vigilance.

Our Loose Lips Sink Ships design takes that warning back to sea: a hard-eyed captain, rough water, and the kind of bold lettering that feels at home on an old wartime poster. It’s a simple maritime reminder that some things are better left unsaid—and that a few careless words can travel farther than you intended.
