Photographic print of O-I_MMdUB-50215 (obtained from the collection object number 50215 of the Mineralogical Museum University Bonn) mounted with copper tape overlapping an Dundee Precious Metals Tsumeb corporate public relations campaign board—addressing it's target audience with "Learn About Some Of The Invasive Alien Plant Species Of Namibia"—inside the Tsumeb Municipality main building entrance hall.

The print is depicting a Smithsonite mineral that was mined in the German colonial OMEG Mine (later the TLC Mine) in Tsumeb; approximately around 1900-1905. Subsequently it went into the possession of the German industrialist Carl Duisberg (I.G. Farbenindustrie AG / IG Farben).
The Bayer AG outsourced the Carl Duisberg collection under a permanent loan contract to the Mineralogical Collection University Bonn in the 1950s, where it is still hosted at present. Questions regarding the heritage of this specific mineral object or the Carl Duisberg mineral collection in general can be addressed to the director of the University Bonn, Germany, Prof. Dr. Dr. h. c.
