Sol LeWitt apparently did not enjoy public speaking so when he stopped by the School of the Museum of Fine Arts, Boston, in 1971, as a visiting artist and lecturer, he proposed making a drawing with the students instead of giving a lecture.
WALL DRAWING BOSTON MUSEUM On a wall surface, any continuous stretch of wall, using a hard pencil, place fifty points at random. The points should be evenly distributed over the area of the wall. All of the points should be connected by straight lines. SOL LEWITT Wall drawing, Boston Museum Pencil 1971
