Long map in leporellobinding and 1st map of the Kasai and the Lulua rivers in the Congo Basin. The river valley, from Kwamouth (northeast of Kinshasa) to Luebo, was surveyed on board of the Steamer "Stanley". The initial sketch by Captain Schageström, corrected by Albert Thys, was completed with information from a German expedition by Hermann Wissmann. Albert Thys, a Belgian businessman active in the Congo Free State, directed the construction of the Matadi-Léopoldville Railway - a project that costed the lives of 1,932 people - and mediated in the appointment of Joseph Conrad as steamer captain.
