Roy Lichtenstein (Tate Gallery Liverpool, 051-709 3223, to 18 Apr). Entertaining, not finally convincing retrospective of the veteran pop artist and Mickey Mouse fan.
Ruskin and Tuscany (Ruskin Gallery, Sheffield, 0742-735299, to Sat). Last chance to see this magisterial account of the great Victorian's trips to Italy. The Great Age of British Watercolours (Royal Academy, 071-439 7438, to Sun). Survey of the golden years of the medium, from 1750 to 1880.
The Sixties (Barbican, 071-638 8891, to 13 June). All-over-the-place exhibition mixes nonsense with high art: an incoherent but exciting attempt to catch the essence of the decade.Reuse content
