We've never been ones who needed an excuse to dress up, so last Thursday we happily headed uptown to the Park Avenue Armory for The Salon Art + Design, generally considered to be New York's fanciest design fair. We've only recently begun attending the Salon in part because the fair has only recently reached a tipping point, where the quality and number of boundary-pushing contemporary pieces matches the number of vintage ones on display — all of which, of course, reflects a more general trend in the collectible design world.
