• The most significant private collection of the paintings and drawings of Frank Auerbach – described as one of Britain’s “greatest living artists” – has gone on show at Tate Britain on Millbank. The works, which span the period from Auerbach’s student days in the late 1940s until 2007, were collected by the late artist Lucian Freud and hung in his London house until his death in 2011. They include portraits of Auerbach’s friends and relatives and landscapes of London. BP Spotlight – Frank Auerbach: Painting and Drawings from the Lucian Freud Estate is on display until 9th November.
