The Poisonous Mushroom (Der Giftpilz in German) was published in 1938 by Julius Streicher’s Stürmer-Verlag. The children’s book is a notorious piece of antisemitic propaganda. Written by Ernst Hiemer and illustrated by Philipp Rupprecht (under the pen name “Fips”), it uses the central metaphor of poisonous mushrooms—appearing harmless but deadly—to equate Jews with hidden dangers that cannot be easily distinguished from good people.
