Curator Martin Clayton cleans 'a study for the head of Leda', drawn in
1505-6, by the late Italian artist Leonardo da Vinci before the opening
of the exhibition 'Leonardo da Vinci: The Divine and the Grotesque', at
The Queen's Gallery, Buckingham Palace, London, May 8, 2003. The show,
which opens on Friday and runs until November 9, explores the
Renaissance master's obsession with the human form, and all 77 works
come from the Royal Collection, which comprises the world's finest
collection of Leonardo's drawings. REUTERS/Toby Melville
