1965, printed 1998, Gelatin silver print with shed snakeskin, collage and ink

Christie's, London

Peter Beard was the wild man of photography, an American who made Kenya his home and turned its vanishing wildlife into epic, blood-and-ink artworks. His book The End of the Game, from 1965, documented the destruction of Africa's great elephant herds and made him famous. This unique, mural-sized print of a huge tusker is one of his most dramatic images, collaged with shed snakeskin and ink in his signature style. It comes from the collection of Prince Hussain Aga Khan, himself a noted wildlife photographer and conservationist, which adds real pedigree. At 70,000 to 100,000 pounds it is one of the pricier photographs in the sale, but big unique Beards have fetched far more.
