Bruno Munari, Drawing the sun. Via Edizioni Corraini, Italy, 2004.
“When drawing the sun, try to have on hand colored paper, chalk, felt-tip markers, crayons, pencils, ball point pens. You can draw a sun with any one of them. Also remember that sunset and dawn are the back and front of the same phenomenon: when we are looking at the sunset, the people over there are looking at the dawn.”
