# Méfiez-Vous. Révéler toute information de guerre c'est servir l'ennemi. Silence [Beware. To reveal any war information is to serve the enemy. Silence]

A shadowed enemy face with a cupped, enlarged ear looms over a soldier, an airman and a sailor drinking together. The headline 'Méfiez-vous' and the line that revealing war information serves the enemy stage an unseen listener as an immediate danger; the French text is the Canadian counterpart of English careless-talk posters.
