Tarnschriften (German: camouflaged publications) were a way to avoid censorship in Nazi Germany between 1933 and 1945. Illegal writings were given an innocent-looking cover and first and last pages.[1] The Communist Party of Germany published about 80% of the camouflaged publications.[2] An estimated 900–1000 publications were issued with up to 40,000 copies printed per title.[3][full citation needed] Most of the publications were written for Germany, but there were also volumes for Spain and Norway, where a speech by Joseph Stalin was given the title "Hvordan kan potetene bevares mot frost" ("How to protect potatoes from frost").[2]
