(AP) -- The Van Gogh Museum says it has identified a long-lost Vincent Van Gogh painting that spent years in a Norwegian attic, the first full-size canvas by the Dutch master discovered since 1928.
"Sunset at Montmajour" depicts trees, bushes and sky, painted with Van Gogh's familiar thick brush strokes.
Museum experts said Monday the painting was authenticated by letters, style and the physical materials used, and they had traced its history.
Museum director Axel Rueger described the discovery as a "once in a lifetime experience" at an unveiling ceremony.
The museum said the painting belongs to an unidentified private collector and will be on display at the museum from Sept. 24.
