During the Warsaw Uprising on 9 September 1944 German officer Erich von den Bach passed on to archbishop Antoni Szlagowski the urn with Chopin's heart. It was kept in Milanówek till 17 October 1945. The archbishop was displaced from occupied Warsaw and moved to Milanówek just 5 days before the heart was transferred. The illustration was created based on the movie frame from German propaganda war chronicle from 1944.
