In February 1947, the housing office of the City of Vienna conducted a search of Luigi Kasimir's apartment at Operngasse 13. The search resulted in the discovery of a total of 13 pictures with an estimated value of several 100,000 shillings , which was determined later . Allegedly, Kasimir's former secretary had hidden the works in the apartment from an impending confiscation. The pictures that were confiscated when they were found were remnants of the Rieger collection, as well as pictures that had belonged to the daughter of the Jewish lawyer Benedikt and which Kasimir was said to have been given to "care". The origin of other images remained unclear.
