NEW SPRING ANTIQUES FAIR FOR NYC? The Art and Antique Dealers League of America is aiming to launch a week-long, citywide art and antiques festival, anchored by a traditional show at the Park Avenue Armory and set to open next year on Apr. 27, 2011. The 100-member league has already secured the armory, and plans to enlist a major museum as beneficiary of the traditional opening-night gala. "The city boasts literally hundreds of dealers and we want to create an entire city celebration with the fair as the centerpiece," says Clinton Howell, the New York-based dealer in English and European furniture who serves as league president.
