15 Sep TREE-SHELLS 3. 1977.

Dunsyre: Wild Hawthorn Press, 1977
11.5 x 7cm, 4pp. Artist's card with a reproduced drawing of a tree by Bernard Lassus of a tree printed green on white and the text: "TREE-SHELLS. Instructions: Apply ear to Tree-shell. Listen for Lakes." The card can be used to create the same auditory illusion as holding a sea-shell to the ear if cupped close enough - hence bringing the sound of water (lakes) to the ear. This is the third of three cards with the same idea but with different illustrations by different collaborators. VG+
