A textbook written by Elvira Bauer in 1936, entitled Trust no Fox on the Green Heath and No Jew Upon his Oath , was designed to show Germans that the Jews could not be trusted. It portrayed the Jews as inferior, untrustworthy and parasitic. A further anti-Semitic children's book entitled The Poisonous Mushroom , written by Ernst Hiemer, was handed out in 1938. Again it portrayed the Jews as worthless subhumans and through a text containing seventeen short stories, as the antithesis of Aryan humanity. The Jew was dehumanized and was seen as a poisonous mushroom. The book included encompassed strands of both religious and racial anti-Semitism towards the Jews. The contents of this book were following themes "How to Tell a Jew", "How Jewish Traders Cheat", "How Jews Torment Animals", "Are there Decent Jews?" and finally "Without Solving the Jewish Question, No Salvation for Mankind".
