In 1949, the forward-thinking Hertfordshire County Council started buying works of art by contemporary British artists to loan to schools. The Pictures for Schools exhibitions took place through the 1950s and 1960s but now, the council says, the service has become less relevant, with children visiting galleries or viewing works online. The initiative was discontinued in 2017 and now the council is selling off 428 paintings from its 1,828-strong collection, including works by artists like Joan Eardley, Anne Redpath, John Nash and John Tunnard, whose Surrealist watercolour and gouache work is one of the highlights of the sale. John Tunnard, Brandis (1944). The Curated Eye, Cheffins Fine Art Auctioneers, Cambridge, UK, 21 March. Estimate £10,000-£15,000. Photo courtesy of Wienerroither & Kohlbacher
