One of the world's most famous art works, the Beethoven Frieze by Gustav Klimt, is the subject of a restitution claim by heirs of the original owner.
The Austrian artist completed the frieze in 1902 as a tribute to Beethoven.
Its Jewish owners were later forced to flee the Holocaust.
The art work is currently owned by the Austrian state and is on display in the Secession museum in Vienna.
Central Europe correspondent Kerry Skyring is in Vienna and spoke to Ildi Amon about the case.
