A treasure trove not only for Kästner fans: The large collection of Erich Kästner's letters contains many previously unpublished letters from Kurt Tucholsky, Heinrich Mann, Stefan Zweig, Astrid Lindgren, Max Frisch, and Bertolt Brecht. The list of famous correspondents of Erich Kästner seems endless and highlights how closely the writer was in contact with almost all prominent literati of his time. The letters, compiled and commented on by Kästner expert Sven Hanuschek, paint a vivid and multifaceted picture of the private and public Erich Kästner. In addition to literary documents, such as those from the time when Kästner was chairman of PEN, the collection includes a variety of private letters, including two letters written by Kästner as a child.
