This envelope dated 23rd October, 1938 shows the advertisement (accompanying a stamped postmark) urging people to visit the anti-Semitic exhibition "Der Ewige Jude" (The Eternal Jew) in Vienna. The Eternal Jew exhibition was a travelling exhibition and had moved to Vienna by August 2nd 1938, through to the 23rd of October of the same year. It was largely an art and photographic exhibition depicting Jewish stereotypes. It promoted the idea that Jews were a danger to the world. There was also an accompanying film which arrived two years later.
Reports from authorities suggested that, wherever the exhibition was situated, there was a direct correlation in the rise of anti-Semitic feelings and violence.
The racism of the German National Socialist Government became embedded in all state institutions by 1938, including the postal service. Outside the Nazi regime this would generally be viewed as vehement racist diatribe, but became 'normal' and 'acceptable' as seen on this most ordinary of objects.
