 | As part of its 250th anniversary celebration, Christie's is offering a rare, full-scale sketch by master British artist John Constable, "View on the Stour near Dedham" (circa 1821–22) at its 'Defining British Art' sale in London on June 30. The sketch is estimated at £12 million to £16 million. Christie's holds the record for a work by Constable, having sold 'The Lock' (1837) for £22 million ($35 million) in July 2012 in London. |  |
 Going even further back in its provenance, in May of 1837, at what is listed as "possibly the artist's sale," the work was sold for £6.10 | Another Constable that Christie's handled in the past few years made headlines for another reason, when it was sold as the work of a "follower of John Constable," for a mere $5,212 (£3,500) in London in July 2013 . The eagle-eyed buyer who scooped it up had it cleaned and then successfully went about having it authenticated as a work by the master himself. Less than two years later, it was consigned to Sotheby's where it sold for $5.2 million. |  The Cornfield (1826); National Gallery of Art, London |
