A postcard has led experts to know a place. In this place, Vincent van Gogh maybe painted his last work.
Wouter Van der Veen, the director of the Institut van Gogh, found a postcard from 1900 to 1910. It showed tree trunks（树干）and roots（树根）growing on a hill side—this, he thought, showed a similar place to that in Van Gogh's Tree Roots. The strange and bright painting is thought to be the painter's last work before he died on July 29, 1890. It was never fully completed.
After he told his ideas to two researchers at the Van Gogh Museum and a vegetation expert, Van der Veen got the good news. Experts thought the inn in Auvers-sur-Oise—150 meters from the Auberge Ravoux, was very much like the painting's place. Van Gogh spent the last 70 days of his life there.
