_soth_____ Claude Monet, Le Grand Canal, 1908

The Impressionist and Modern 52 lots had a total of £121–164 million estimate which reached a realised total price of £170.3 million. 46 of these lots from the Impressionist and Modern section were sold. The Surrealist pieces had a £18–26 million estimate for 23 lots, 18 of those lots sold for £16.2 million.

The £139–190 million estimate was a record-breaker for Sotheby's as the evening Impressionist and Modern art sales was the best the department has seen as 85.3% of the lots sold for £186.4 million.

Sotheby's had guaranteed 12 lots, six of which had irrevocable bids from a third party, and a low estimate of £60.4 million, the largest amount the department has guaranteed outside of the US.

The highest selling lots included pieces by Claude Monet, not a surprise as five Monets featured in the sale, reaching £55.7 million. Le Grand Canal in Venice, 1908 sold in 1989 for £7.5 million. In 2005 it then went on to sell for £8.5 million. The painting sold this week for £23.7 million.

Other impressive sales included Toulouse Lautrec's Au lit: le baser, 1892 which sold for £7.7 million to an anonymous phone bidder against dealer Thomas Seydoux, which was a new record for a work on paper by the artist.

The highest un-guaranteed lot was Matisse's Odalisque au fauteuil noir, 1942, which previously sold in 2004 for £6.6 million and sold this week for £15.8 million.

Two Picasso sculptures from the estate of the dealer Jan Krugier was first on sale at Christie's in New York in 2013 but failed to sell. The wooden sculpture of a naked boy sold this week for £869 000 to Acquavella Galleries. An iron and steel maquette which was made for Chicago's Civic Centre in 1964 sold to a telephone bidder for £8.9 million. Finally, Picasso's sculpture La Chouette set a record for a Picasso terracotta which sold to Alex Platon of Marlborough Fine Art for £1 265 000 against a pre sale top estimate of £450 000.

Magritte's L'explication sold below its estimate of £3.7 million. Kurt Seligman's surrealist piece Witches, 1950 sold for three times its estimate for a final hammer price of £173 000.
