The range at Masterpiece which opens in London today – from the Hongs of Canton in 1772 to Maverick House, Boston in 1837 to Crowther Street in Stockport in 1964 – is vast. Among many highlights is an uncatalogued work by Claude Monet at Richard Green; one of the large known fancy vivid yellow diamonds weighing over 114 carats by Symbolic and Chase; a 45 metre tall painting by Robert Delaunay whose wife Sonia is the focus of a retrospective now on at Tate Modern and The Fibonacci – the 600,000th piano by Steinway and Sons, who are Fair Partners. Masterpiece runs from June 25 to July 1 at The Royal Hospital in Chelsea, with a preview day on June 24. Here are some masterpieces:
