We are honored to present a large group of fine old classic specimens from the extensive collection of Bill and Anne Cook, of Cleveland Heights Ohio. They collected, together, for over 60 years and this collection represents an astonishing depth of interests and knowledge of all kinds of minerals. The collection is particularly strong on associations, pseudomorphs, and classic localities. Look for further auctions of this rich and diversified collection, in the several years ahead.
