" cocteau insists that the idea of tank camouflage came from picasso who suggested it to a french war minister before the great war as a means of making soldiers invisible. cocteau also asks himself whether savages don´t paint their skins less to make themselves frightening and more to make themselves invisible. that is a good idea. you make things invisible by destroying their form, giving them an unexpected form, making them as it were not inconspicuous, but at once striking and strange.
the germans are marching on paris."
