The catalog of the Philadelphia Antiques Show in 2013, which featured an important loan exhibition of early Pennsylvania pewter.  This catalog includes a significant, illustrated multi-page essay entitled "Pewter:  The Philadelphia Story" by Donald M. Fennimore, former curator at Winterthur and noted author on American metalwork, etc .  The article includes several images of loaned items exhibited and traces the evolution of pewter making in Philadelphia from the eighteenth into the early nineteenth century.  Images of significant forms abound, including the William Will coffeepot on the cover, which more recently sold for $237,500 from the Wolf collection.
