Blue hardcover book “Encyclopedia of American Silver Marks” by Dorothy Rainwater. Second publication- May 1978. Does not have dust jacket. In great condition. I noted writing on the interior of the back cover (shown in photos). I did not note any other writing. All pages intact, no rips or tears. The spine and cover are in good condition. Great resource for silver collectors with minimal wear. Some photos (black and white), but mostly names and information on manufacturer’s and their markings, dates, etc. Published by Crown. ISBN 0-517-521-458. Encyclopedia, silver, collector, resource, marks, guide, index, hardcover, non-fiction.
