 Posse also purchased over 200 pieces which Jewish owners had managed to get into Switzerland, where they were safe from expropriation.On the other hand, Posse did not shy away from confiscation either, particular in the former Czechoslovakia and Poland, where all property was subject to it, but also in the Netherlands.It is not possible to determine with any accuracy the size of the collection which had been amassed for Hitler's planned museum in Linz, but Frederick Spotts suggests that something around 7,000 pieces had been confiscated, bought or purloined specifically for the "Führermuseum", and that others from the many other art repositories scattered around Germany would most probably have been added had Hitler won the war and he and his art experts had the opportunity to sort through the artworks and assign them to various museums.
