The exhibition is built around a Yuan dynasty hanging scroll: dead trees, a far bank and water pushed apart in washes of pale ink, the artist's own line of inscription at the upper right, seven or eight collectors' seals stacked at the corners, the topmost worn to a ghost of its outline.
Two colophons are shown in facsimile; the talks start from the order of the seals, which tells you how often a painting changed hands across four centuries. Forty visitors per session, entry by reservation.
