Since 1956, the antiques dealers of Paris have organized a bi-annual show that's non pareil. This year's Biennale des Antiquaires promises to be different than in previous years, a nod to the fact that even though the mood of the event is steeped in the heavily adorned antiques of the 18th and 19th centuries the mode is definitely streamlined 20th century. The fair is shorter (10 days down from 17), and the number of dealers is down from 118 to 104, allowing for a more spacious layout and exhibition space. Nonetheless, the show is likely to display the drama that it has come to be known for as Jacques Chatelet, a Parisian lighting director for stage, opera and ballet, has been called in to infuse the subterranean exhibition area, located in the depths of the Carrousel du Louvre, with an abundance of light. Mark the calendars for September 20 through 29.
