Nazi-looted French painting on display in search for rightful owner

A 19th-century oil painting stolen from occupied France during World War II has gone on display in a bid to trace its rightful owners. This happened after it was returned by the son of the German soldier who took it on orders from above.

After 76 years in Germany, the small untitled artwork by French painter Nicolas Rousseau is back in France and exhibited at the World Centre for Peace, Liberty and Human Rights in the northeastern town of Verdun.

Next to it hangs a sign: "If you recognise the landscape or have any information about this painting, we would be grateful if you would let us know."

For the last fortnight, it has hung in the lobby of the centre, which receives around 60,000 visitors a year, in the hope it will nudge someone's memory and lead the painting back to its owners or their heirs.

In the artwork, a figure sits on a river bank under cloudy skies, surrounded by tall trees and with a village off in the distance.

Rousseau was a member of the Barbizon school of painters, who embraced naturalism in art.

Its reported true value goes far beyond its market value of 3,000 to 5,000 euros ($3,580 to $5,970).

In spring 1944, Alfred Forner, an NCO in the German Luftwaffe, was stationed somewhere between France's northern Normandy region and the town of Saint-Omer further up the coast. He was commissioned by a superior to bring the Rousseau painting to Berlin during his leave.

But when he got to the address in the German capital where he had been told to take the canvas, he found the building in ruins.

Forner died in combat some months later, during the summer.

The artwork, which measures 38 x 55 centimetres (15 x 22 inches), hung on the family's living room wall in Berlin for 75 years.

But in January last year, his son Peter Forner contacted the French embassy in Berlin, expressing the wish that the painting be returned and its owners found.

By exhibiting the painting -- a move he said was unprecedented -- they hope to identify the owners but also to carry out the last wishes of Peter Forner, who died in May aged 80.

An official ceremony of restitution is due to be held in October at the World Centre for Peace, housed in an archbishop's palace.

The painting will then join an exhibition on the end of WWII, planned for the close of the year.
