最新发现的梵高作品《蒙马儒落日》

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.
