This is a beautiful cover from a refugee named F Kreisky in the Jewish ghetto in Shanghai China to the Jewish Welfare Society in Melbourne Australia. Great cancels and markings. In excellent condition. Postmarked April 1, 1947. Before and during world war 2 many Jews fleeing Nazi persecution took refuge in Shanghai China forming a ghetto. After the war, with the Nazi's defeated, and civil war in China heating up, many sought to go to Palestine or the USA.
