Acknowledgments

Book are the product of many busy hands, so it is only proper that I begin by acknowledging the corporate hands of the many institutions that allowed me to cite or reproduce material in their collections. In particular, I would like to mention the Art Institute of Chicago; the Chester County Historical Society, West Chester, Pennsylvania; the Deutsches Brodmuseum in Ulm, Germany; Doe Run Valley Books of Chadds Ford, Pennsylvania; the Henry Francis DuPont Winterthur Museum, Winterthur, Delaware; the Kulturgeschichtliches Museum Osnabrück, Osnabrück, Germany; the Library Company of Philadelphia; the Library of Congress; the Philadelphia Museum of Art; the University of South Carolina Press; the Van Pelt Library of the University of Pennsylvania; the Wyck Association of Philadelphia; and the York Castle Museum, York, England.
