Letter from Winifred Wagner to Fräulein Bötticher, 1931 September 22. "Dear Fräulein Bötticher. The Liszt Museum exists in Weimar. I believe that the curator, Professor Peter Raabe is in Aachen. In any case, the city of Weimar or Raabe could give you information. Frl. Helena Wallem in Bayreuth Neues Schloss could perhaps also be interested in Liszt's letters for her Richard Wagner Museum. Sincerely, Winifred Wagner"
