Cubist Slugs: "'I well remember at the beginning of the war,' Gertrude Stein wrote in 1938, 'being with Picasso on the Boulevard Raspail when the first camouflaged truck passed. It was at night, we had heard of camouflage but we had not seen it and Picasso, amazed, looked at it and then cried out, yes it is we who made it, that is Cubism.' Stein went on to suggest that the entire First World War had been an exercise in Cubism."
