BOONTON, N.J. — An ancient Roman-style mosaic led “Select,” a three-day online auction presented by Millea Bros, May 18-20, that offered a wide range of art, design and antiques sourced from prominent New York area estates. The mosaic sold on Day 3, a session devoted to Asian and tribal arts, antiquities and silver. The large marble panel featuring a pouncing spotted panther among grasses and a tree branch jumped its $10/15,000 estimate to sell for $262,500. Possibly from the Fourth-Fifth Century, the 66-by-74-inch mosaic on a cream ground was property from the collection of a media executive and had further provenance to the Merrin Gallery in New York City as well as a Japanese private collection, acquired from Alain de Monbrison, Paris, in 1988 (by repute). Day 1 was devoted to Modern and contemporary art and design, jewelry and fashion, while Day 2 featured American, European art and antiques and carpets. The three-day sale total was $2.9 million. A later review will present more highlights.
