Lehner's Encyclopedia Of US Marks On Pottery, Porcelain Clay
This thick hardcover book is packed with text and illustrations, the sheer measure of which admittedly took the author nearly a quarter century to research and compile. The book is an indispensable aid for properly identifying pottery, porcelain, and clay pieces. The various manufacturer listings contain paragraphs outlining the history of each company as well as interesting "insider" information. Both the novice and veteran collector can ID their merchandise quickly and easily. -K. DeCiantis
