In this French poster of 1918 for the 4th National Defence Loan, the Gallic cockerel and the Imperial German eagle face each other. During the First World War, these National Defence Loans were used by the French government to raise money. Unsurprisingly, the length of the conflict and the amount of material used meant that the war effort was a costly exercise. The civilian society was invited to contribute with their savings. To convince the Home Front, a vast range of posters and postcards playing on patriotic feelings was printed in order to mobilise the rear and make it feel involved.
