"Shame on you, chatterer! The enemy is listening. Silence is your duty."
Before World War II began, Germans were allowed to listen to foreign radio broadcasts. This was banned once the war began, and by the end of the war people were executed for listing to enemy radio stations. In this poster, a Marxist looking chap broadcasts from London, Moscow, and other enemy states, while a German listens in the darkness, trying to conceal his crime.
“Before: Unemployment, hopelessness, desolation, strikes, lockouts. Today: Work, joy, discipline, comaradarie. Give the Führer your vote!”
