The Artist at Work: William Coldstream and Michael Andrews 19 January–11 May 2008 Based on Colin St John Wilson’s book detailing his experience of sitting for both artists, this exhibition draws on the Wilson Collection to highlight the working practices of Coldstream (1908–87) and Andrews (1928–95). Coldstream, known for his methodical grid-based compositions, was Andrews’ tutor at the Slade School of Art but encouraged a freer approach in his pupil that found its fruition in the late Thames Paintings of the 1990s, which feature in the show.
