Three objects from the Nazi-confiscated collection of Louis Rothschild came into the possession of the MAK. Two objects were returned in 1949 already; for the third, a carpet, restitution was recommended by the Advisory Board on 11 February 1999, which eventually took place on 11 March 1999.
Provenance research about MAK purchases after 1945 showed that a gambling table which, in the Nazi era, was supposed to go to the then-planned museum in Linz and was handed over to the museum by the Federal Office for the Protection of Monuments in 1963 had been in the collection of Louis Rothschild until 1938.
On 11 September 2009, the Advisory Board recommended the restitution of the object.

On 2 March 2010, the gambling table was returned to the heirs of Louis Rothschild, who then donated it back to the MAK.
