FALLS CHURCH, VA.- When it comes to elegant residential decor and grand ambassadorial-style hospitality, few American cities can match Washington, D.C. A hub for international diplomats for centuries, it has long been known as a sweet spot for tasteful antiques and artworks, such as those to be auctioned Sept. 10, 2011 at Quinn’s & Waverly in suburban Falls Church, Virginia. A special Sept. 8 offering of antique books, maps and autographs; and a Sept. 7 session devoted to antique pewter will precede the main sale. The company’s Sept. 10 Fine & Decorative Art sale includes a wealth of treasures from D.C.-area homes, including a superb Tiffany & Co. antique sterling silver flatware service for 12 and a striking hand-painted and glazed Picasso ceramic pitcher. Representing the highest quality in American decorative arts, the Tiffany name has never fallen out of favor with bidders at Quinn’s auction events. F
