Amsterdam's Van Gogh Museum has unveiled a newly discovered painting by the Dutch master Vincent Van Gogh.
The museum on Monday revealed "Sunset at Montmajour," a large oil landscape.
Museum officials say the painting had been in the attic of a Norwegian collector who thought the painting was a fraud after buying it in 1908.
They say the painting was authenticated by letters, style and the physical materials used.
Museum officials described the discovery as a "once in a lifetime experience."
The painting will go on public display at the museum on September 24.
