Andy Warhol: The Portfolios

If you've seen one Andy Warhol silkscreen, you've seen them all, right? Some of his starlets might indeed be a little tired around the eyes in 2012, but this suite of 80 prints by the shock-headed pop maestro seem temporarily Botoxed by their neighbouring Old Masters. Bypass the usual suspects if you must – the 'Campbell's Soup Cans', the 'Flowers' and a 'Marilyn' flanked by four fussy sunsets – and head instead for the central galleries. There, gems plucked from 13 portfolios of Warholia really sparkle; quite literally in the case of the diamond dust prints, which include a moody self-portrait of the artist as 'The Shadow'. (FB)
