Poussin’s strictly private appeal

The rediscovery of a significant work by a major Old Master painter is always an event for the art trade, even if the work not obviously commercial. When Anthony Blunt wrote his monograph on Nicholas Poussin (1594-1665) this painting, right, of The Holy Family with St. John the Baptist, executed c.1627-28 when the young Poussin first worked in Rome, was only known from engravings.
