The students at the Robinson Crusoe Kindergarten, with their teachers, post bills around the city to promote an event linked to their experiences and and activities fulfilled by them. The bills are unique and diverse from one another as specifically drawn by the children. The evening for such an event, as the bills state, is: March 17th, 1972, 9 o'clock pm. The children, equipped with glue, brushes and stairs, move around the districts on a yellow schoolbus.
