A Vincent Van Gogh painting that was discovered in a Norwegian attic has been unveiled in Amsterdam in what is the first discovery of a full-sized canvas by the Dutch master since 1928.
'Sunset at Montmajour', pictured, a landscape of trees and sky in the south of France in Van Gogh's familiar thick brush strokes was painted in 1888 but has been lying in the attic of a Norwegian collector who bought the painting in 1908 but dismissed it as a fake.
The painting was unveiled at the Van Gogh Museum in Amsterdam yesterday, with Axel Rueger. the director, describing it as a "once in a lifetime experience".
The painting was authenticated based on comparisons with Van Gogh's techniques and a letter he wrote in which he described the painting.
It can be dated to the exact day it was painted because Van Gogh described it in a letter to his brother, Theo, and said he painted it the previous day – July 4, 1888. He said the painting was done "on a stony heath where small twisted oaks grow".
Researcher Teio Meedendorp said he and other researchers "have found answers to all the key questions, which is remarkable for a painting that has been lost for more than 100 years".
The painting was listed among Theo van Gogh's collection as number 180, and that number can still be seen on the back of the canvas. Mr Rueger said the museum rejected the painting's authenticity in the 1990s, in part because it was not signed. But new research techniques had convinced them.
The long-lost work was painted at around the same time as some of Van Gogh's most famous works, including 'Sunflowers' and 'The Bedroom'. (© Daily Telegraph, London)
