Once strapped around your face, the Pencil Mask (1972) transforms the head into an instrument for drawing.

Rebecca Horn has described wearing it: “All pencils are about two inches long and produce the profile of my face in three dimensions…I move my body rhythmically from left to right in front of a white wall. The pencils make marks on the wall the image of which corresponds to the rhythm of my movements.”

Rebecca Horn’s Bodylandscapes is at the Hayward Gallery, London SE1, till Aug 29.
