Adults and children sometimes have boards in their bedrooms or
living-rooms on which they pin pieces of paper: letters, snapshots,
reproductions of paintings, newspaper cuttings, original drawings,
postcards. On each board all the images belong to the same language and
all are more or less equal within it, because they have been chosen in a
highly personal way to match and express the experience of the room's
inhabitant. Logically, these boards should replace museums.
