Gustav Klimt is one of my favourite artists (him and Frida Khalo) so when I was asked to photograph his Bauerngarten, the star of  Sotheby’s  Impressionist & Modern Art Evening Sale on 1 March in London this year prior to it’s sale you can probably imagine how excited I felt. “Innovative in its composition and jewel-like in its exquisite blaze of colours, it is one of the artist’s greatest masterpieces ever to come to auction.” It sold for £48 million and is now the third most expensive painting in European history.
