Africa orientale possedimenti tedeschi 1892 Sohr-Berghaus scarsa mappa a colori dettagliata
(Issued 1892, Glogau by C. Flemming for Sohr-Berghaus. Fascinating map, utterly unique to the publisher and date- a large detailed inset box occupying mush of the left side titled _"Das Mittlere Ost-Afrika".).
