The design source for this chair is illustrated in George Hepplewhite's The Cabinet-Maker and Upholsterer's Guide (London, 1794), plate 4g. The shield back employed on this chair was frequently used by both New York and Rhode Island cabinetmakers. These chairs, with ash secondary woods and finely carved shields, are thought to be Rhode Island.
