On the invitation of Professor Frank Heidemann, Chair of Visual Anthropology, Institute of Ethnology at the Ludwig-Maximilians-University in Munich, I presented the work and a thematically related experiment by the Africa expert Hans Himmelheber to students, thus recapitulating a joint exhibition that had been shown in Munich in 2004 at the Staatliches Museum für Völkerkunde (since 2014 Museum Fünf Kontinente), the Iwalewahaus (Bayreuth) and the Kunstverein Aalen.
