A WWI poster from the British National War Savings Committee urges restraint in the use of materials during war time. It's better to spend on war bonds: "To dress extravagantly in war time is worse than bad form, it is unpatriotic." Printed by Roberts & Leete, Ltd., London, 1915.
Tell Her Nothing (1940). Produced quite early into World War II, this extremely rare British poster proved so popular that as soon as the posters were put up, they would disappear – presumably stolen by amorous servicemen. This woman was a more popular pin-up than Vera Lynn in the early war years. We would tell her everything. And give her the blueprints (whatever blueprints are).
