Soon after completing the 'La Combe' series [circa 1950] I had a dream in which I was assisted by many children on a scaffold, painting a huge mural made up of square panels fitted together. Each panel was being painted by a child very quickly in long black strokes with huge brushes. The work was done in seconds. Upon waking I immediately made a reminder sketch of the mural. Later I made a drawing of many ink strokes, which I cut up into twenty squares and placed at random in a four-by-five grid..
