Shark Ed. 150 (1986)

One of the marine life designs the artist produced while working at Caithness. Cruising above the ocean floor is a solitary shark - his streamlined body beautifully captured in glittering blue aventurine, his jaws slightly apart. A spotted blue crab and a small green fish seek what cover they can in the colourful acquatic plants.
Acid-etched on the flat, polished base: Caithness Shark Scotland. The original certificate states that the weight was designed and made by William Manson.
(Originally planned as an edition of 150, only 123 were actually produced. This is number 74).
