This Philadelphia side-chair represents one of the most elaborate interpretations of the Gothic rococo and is derived from plate XVI of Thomas Chippendale's Director (1762, edition). A chair from this same set is illustrated and discussed in William Macpherson Horner, Jr. Blue Book, Philadelphia Furniture (Washington, D.C., 1935), pl. 362. Four chairs from the set are now in the collection of Teh Philadelphia Museum of Art. A fifth chair from the same set, now in the collection of George and Lina Kaufman, is illustrated and discussed in J. Michael Flanigan, American Furniture from the Kaufman Collection (New York, 1986), pp. 32-33, no. 9. A nineteenth century photograph of three of these chairs in the parlor of C.W. Wharton's house on Spruce Street, Philadelphia exists (See Flanigan, p. 32).
