This 1995 book by the recently-departed Dr. Donald M. Herr revealed the existence of many hitherto unknown and important American, English, and German pewter flagons, beakers, communion cups used ecclesiastically in Pennsylvania in the 18th and early 19th centuries.  Marvelously researched,  well-documented, and lavishly illustrated, it remains a "must-have" for collectors.  Very good, used condition.  Hardbound, 214 pp.
