Póster Paul Verlaine's Poem on a White Paper

For the Operation Overlord, BBC's Radio Londres signaled to the French Resistance on June 1 1944, that the Normandy Landing will start within two weeks, using the first three lines of Paul Verlaine's poem, chanson d'automne: les sanglots longs des violons de l'automne On June 5 at 23:15, they send the next set of lines: bercent mon coeur d'une langueur monotone; meaning, that Operation Overlord will begin within 48 hours and signaling to the resistance the green light to do sabotage operation, especially on the French railroad.
