Running until July 7 at galleries around the city, with concentrations in Mayfair, St James’s and Cromwell Place, the shows also attracted private collectors from around the world.
At John Mitchell Fine Art, a European private collector bought three Edouard Vuillard (1868-1940) artworks with a combined price into six figures.
The exhibition, French Masters on Paper, from Degas to Matisse included Impressionist and Post-Impressionist works covering the years from 1878-1942 with prices ranging from £25,000-450,000.
A private collector bought a Ptolemaic period (304-30BC) limestone relief with an owl from Rupert Wace, which had an asking price of £20,000-30,000.
Colnaghi Elliott reported a batch of sales including a black chalk Study for an Old Man’s Head by Pauline Auzou (1775-1835) which sold for £15,000.
A number of galleries said museums had reserved artworks for purchase and many of the exhibitions continue further into July following the end of LAW.
