No. 89 - arriving mail art "Who knows about Mrs. Bismarck?" from Angela Behrendt (Germany)

No. 89 - arriving mail art "Who knows about Mrs. Bismarck?" from Angela Behrendt (Germany) - the first add&pass sheet from Lothar Trott arrived already (see here: http://bismarck-mail-art.blogspot.com/2009/08/no-84-arriving-mail-art-who-knows-about.html), here the modification from Angela Behrendt. She refers to the wife of Bismarck, Johanna. Angela has sent as well the original envelope he got from Lothar without using a valid postage stamp. Thank you very much.
