- confiscated collections from German and Austrian Jews were among the first acquisitions for the musem. What was possible earlier in Germany became formally legal in Austria in November 1938. From then on the "Reichsstatthalter" (as the Austria provincial government was called), could take possession of the "property of persons or associations of persons supporting aims detrimental to the people or state" for the benefit of the State of Austria. (Paper of Regulations for the State of Austria, Item 167 No.589)
Because of the so-called "Führer's proviso", Hitler himself determined the use of the confiscated art objects.

- best items from the Alphonse Rothschild collection were chosen for the museum in Linz.
- after WW2 started, works were taken out of Warsaw and Krakow

- purchases in Italy became so extensive that the Italian ministry felt compelled to pass a new law prohibiting the export of art works.

- in 1943/44 , 3000 paintings worth 150 million Reichsmark, despite all the financial burdens of the war, were purchased for the projected Art Museum in Linz.
