The Butterfly Ginkgo Collection celebrates the representation of flora as fauna. Michael's fascination with a particular type of ginkgo tree, the ginkgo Biloba, or "Butterfly ginkgo", which grows with a double leaf reminiscent of a butterfly's wings, gave rise to a fantasia image of the plant. Executed at the highest level of handcraftsmanship, each piece is rendered in solid bronze with acid etched cocoon-shaped vessels.
