The years of warfare were the backdrop for art which is now preserved and displayed in such institutions as the Imperial War Museum in London, the Canadian War Museum in Ottawa, and the Australian War Memorial in Canberra. Official war artists were commissioned by the British Ministry of Information and the authorities of other countries. The Cubist vocabulary itself was adapted and modified by the Royal Navy during "the Great War." The Cubists aimed to revolutionize painting — and reinvented the art of camouflage on the way.
