CANDIA, N.H. — While Schmitt Horan & Company is best known for its horological auctions, the firm’s August 9 online auction also included American and European paintings, art glass, inkwells, tobacco jars, automata and music boxes, coins, rare books and more. Nearly 290 lots were on offer, and it was a Nineteenth Century double singing bird box attributed to Bontems, Paris, and retailed by Finnigans, London, that reached the sale’s highest price. Selling to an online buyer for $26,400, including buyer’s premium — a significant improvement upon its $8,000 high estimate — the 1½-by-4-inch rectangular turtle shell case was topped with a golden oval cover that opened to reveal two brightly colored bird performers. A future issue will contain more highlights from this sale.
