Kang Collection (9 East 82nd Street), one of the relatively few dealers to specialize in Korean art, should be included in any Asia Week itinerary; it’s just steps from the Metropolitan Museum of Art and has supplied some of the items in the Met’s collection. It’s now featuring court paintings of the Joseon dynasty (1392-1910), among them an eight-panel folding screen from a gentleman’s study that depicts bronzes and fruit bowls resting atop piles of books.
