A court in Germany has ordered a museum to hand over thousands of vintage posters to the son of their original Jewish owner.

The artwork - said to be worth millions of dollars - was initially seized by the Nazis and later ended up in a museum in Berlin.

The debate over who should be considered the rightful owners has lasted for many years.

But now Germany's highest court has said that not returning the posters would perpetuate crimes carried out by the Nazis.
