|Drawing for The Exquisite Corpse by Victor Brauner, André Breton, Jacques Hérold and Yves Tanguy, 1935.|
With a large brush spread black gouache, more or less diluted in places, on a sheet of smooth white paper that you will immediately cover with a similar sheet on which you exert a medium pressure with the back of your hand. Lift this second sheet slowly by its upper edge, just as you would proceed in decalcomania; refrain from reapplying it and raising it again until drying is almost complete. What you have before you is perhaps only da Vinci's old paranoiac wall, but it is this wall perfected. It may suffice, for example, to entitle the image obtained according to what you discover there, first withdrawing somewhat in order to ensure the most personal and valuable expression.
