You remember the old war time expression, "Loose Lips Sink Ships ! " That implied that service members should not be talking to people outside of the military service about their mission or location....that might allow sensitive information to get into the hands of opposing forces. Here's a vintage style poster made into a USA-made metal sign that tells our service members to serve in silence during war and let the military ships and aircraft do the "talking" for America to their adversaries.
This "Serve In Silence" Vintage Metal Sign measures 18 inches by 12 inches and weighs in at 2 lb(s). This Vintage Metal Sign is hand made in the USA using heavy gauge American steel.
