Striking images of Welsh mining towns in the 1960s are set to go to auction in the US.
The 10 black and white works, taken by US photographer Bruce Davidson almost half a century ago, will go under the hammer at a Sotheby's sale in New York on April 6.
They are expected to achieve a combined $10,000, a figure that is sure to tempt art and photography investors.
Davidson was sent to Wales in 1965 to capture images of the Welsh countryside and castles by images agency Magnum.
But Davidson instead decided that he wanted to show the real life Wales in the mining villages of the Valleys.
Dr Cabuts, a photography academic at the University of Wales, Newport, told the Western Mail: "He was quite influenced by Eugene Smith and follows in some ways the black and white tradition of miners and valleys and so on."
In 1950 Smith famously portrayed three Welsh miners for the front cover of Life magazine.
Each of the 10 photos, printed in 1982, is signed in pencil on the reverse and has a portfolio stamp.
