Paix et Liberté.

Jean-Paul David, mayor of Mantes, Deputy from Seine-et-Oise and Radical Socialist Party politician created Paix et Liberté in the fall of 1950. David hoped the agency would expose the lies presented to the French public through the posters published and distributed by the French Communist Party (Parti communiste français, PCF). The PCF had developed an extremely successful billboard campaign using the 1949 drawing of Pablo Picasso's peace dove, which he created for the PCF's World Committee of Peace Partisans conference held in Paris in the spring of 1949. The success of this poster in particular spurred David, with the support of Premier Ren ̌Pleven, to organize a semi-private, anti-Communist agency. This agency published and distributed posters supplemented by newsletters, brochures, pamphlets, stickers, and tracts that used the words, themes and symbols of the Communist Party to counter their message.
