Though the publisher's name of this edition is Horst Sander KG, it's an Eulenburg edition (see worldcat). After Eulenburg was expropriated by the Nazis in 1938, Sander bought the company in 1940. Moreover for this "new edition" the editor's name (Alfred Einstein) was presumably removed from the preface (German / English). --Ralph Theo Misch 19:15, 19 June 2011 (UTC)
