As per a new report, a claim has been filed by the families of all those who fled Vienna in 1938. The claim has been filed for their return of one of the country's national treasure.

The heirs of Erich Lederer, wealthy Austrian Jews, have been asked for the repayment of the Gustav Klimt's 1902 creation, `Beethoven Frieze'. Theses heirs were the important patrons of the famous artist Gustav Klimt.

Claudia Schmied is the country's minister for education arts and culture. The claim was filed with the government's Art Restitution Advisory Board, which will advise Claudia to take some important decisions.

The disaster, which took place in 1938, forced the family members of the Lederer fled Austria in 1938. This disaster caused damage of the extensive art collection, valuable artworks of Erich along with the 18 art collection by Klimt.

The `Beethoven Frieze' was among the finest creation of the family, which was returned to them by the government after World War II.

But later the state demanded the family to sell the frieze to the government. They did so in order to export the rest of the art work recovered of the family's art collection to Switzerland.

The state offered the family to sell the frieze for half its value. The family has been forced to sell their work under the law, which was passed in 2009.
