Edvard Munch's famous masterpiece The Scream is to be sold at auction in New York, Sotheby's has announced.
The Norwegian artist created several versions of the artwork, using different techniques.
The 1895 work, which is going under the hammer in May, was created using pastels and is the only version still in private hands.
A Sotheby's spokesperson has suggested the artwork's price tag could exceed $80m (£50m).
