Portraits of the expansively bearded postman Joseph Roulin, his wife, two sons and baby daughter have been brought together for an exhibition titled “Van Gogh and the Roulins. While preparing the show, the Van Gogh Museum found the very chair featured in the portrait in its storerooms and is exhibiting it for the first time. “As it turns out, we have this chair in our collection, but we have never shown it before,” said Van Gogh Museum Director Emilie Gordenker. She said that the chair went into storage after Van Gogh left Arles and was then passed to the artist’s relatives and ultimately to the museum. The museum is now displaying the chair alongside the painting from the Boston museum that features Roulin and the chair.
