GOFFSTOWN, N.H. — John Dunlap is one of New Hampshire’s best known Eighteenth Century cabinetmakers. On July 28, in its first sale under its new name, New Hampshire Auctions and Appraisals had a number of items related to Dunlap and his extended family, some of whom were also cabinetmakers. All came from a Dunlap family home and the three highest priced items in the sale were Dunlap-related. Selling to Woodbury, Conn., folk art dealer David Schorsch for $51,000 was a double portrait of John Dunlap in his militia uniform and his wife, Martha. Dunlap was a major in the Ninth Regiment of the New Hampshire Militia. On board, the double portrait by an unknown artist had descended in the family and had never previously been offered for sale. Another primitive portrait of Dunlap alone brought $9,000, the third-highest price of the sale, $9,600. The second-highest priced item, far exceeding the estimate, was an Eighteenth Century molding plane that had belonged to, and presumably had been used by John Dunlap. It brought $18,000. There were several other Dunlap related items in the sale, along with a rare Shaker rocker, trade signs and clocks. A full report will follow and prices include the buyer’s premium.
