One of the most famous paintings in the world will go on show later this week ahead of its sale.
The Scream, by Norwegian painter Edvard Munch, is expected to fetch as much as 80 million US dollars (£50.4 million) when it is sold in New York on May 2.
The work, one of four versions of the painting created in the 1890s, will be on view in Sotheby's in London.
It is the only one of the four still in private hands and is owned by a Norwegian businessman, Petter Olsen, whose father Thomas was a friend and patron of Munch.
It has never been on public view in either the UK or US except for briefly in the National Gallery in Washington DC.
The instantly recognisable painting has been the subject of countless books and articles and is Munch's most famous work.
The artist, who died in 1944, studied engineering before embarking on a career as an artist in Paris, Berlin and his native Norway.
