More than 1,300 people strolled through a rich array of decorative arts recently at the 52nd annual Greenwich Antique Show. Westport, Connecticut, dealer George Subkoff displayed a fierce Penobscot Indian wooden ceremonial club that a customer was to claim for $4,800. Sales were 'good' with plenty of interesting objects on display, from 'tobacco leaf' Chinese export porcelain at Philip Suval to a 19th c. warthog skull on a William and Mary table at Keith Funston, Jr.
