The 1948 "Leipzig" was the first post-World War II Baedeker and the last one to be published in Leipzig, which was now in the Russian zone. The Russians had not granted Baedeker a publishing licence. Hans got round this by having 10,000 copies printed by the "Bibliographisches Institut." However, after some 1000 copies had been sold, the Russians said the guidebook contained military secrets in the form of a map showing the site of their "Kommandantura", and confiscated the remaining copies.
