When 150 venerable antiques dealers set up shop in Houston for three days of show and sale, then it must be time for the Houston Antiques Dealers Association Show & Sale. HADA is the nation’s oldest antiques association, and this year’s sale is amped up. Thursday, September 16, is the coveted preview cocktail party, co-hosted by PaperCity, where you’ll get first dibs on treasures and meet and greet design greats who will be signing books and speaking throughout the show. The local, national and international antiquarians are vetted, with offerings as diverse as European and American antiques to Georgian silver and antique maps. New this year and adding buzz to the pomp are the Collector’s Nook of treasures under $200 and “Ask a Decorator,” where you can sign up to spend an hour with an ASID designer. Don’t miss the PaperCity Style Salon and Book Boutique, with designers flying in for book signings and talks, including Hutton Wilkinson, legendary artist and designer Tony Duquette’s protégé and business partner, who will sign Tony Duquette and More Is More: Tony Duquette; designer Jan Showers signing Glamorous Rooms; architect and designer Bobby McAlpine signing The Home Within Us: Romantic Houses, Evocative Rooms; and a host of others. HADA Antiques Show & Sale, Friday through Sunday, September 17 through 19, at the George R. Brown Convention Center. For dealers, show times and Style Salon speakers schedule, go to hadaantiques.com.
