A year ago the Winter Antiques Show changed its definition of antique, from objects more than 100 years old to those made before 1960. Fortunately this allowed for the appearance this year of an eye-catching, whimsical chandelier from 1920, brought by Frank & Barbara Pollack. The piece consists of three wrought-iron arms, each cut into a silhouette of an elk, with hanging acorn-shaped lights. It was love at first site for one visitor, who snapped it up for a five-figure sum soon after the opening.
