Careless Words Can Liquidate Ships -- Better Button up Those Blabber-Lips
Security poster from an Army airfield: a ship splits in two inside a red-and-black explosion, above a rhyming warning in script and block type and a row of lips sealed with crossed buttoned straps. The tell is the fear-appeal that speech alone sinks ships, paired with a slogan of order to keep quiet.
