A woodburytype print measuring 103 x 166 mm. mounted as the frontispiece to Walter Montagu Kerr, 'The Far Interior' (2 vols. London 1886). The half length studio portrait shows Kerr in an open necked shirt and a bush hat standing in front of a backdrop of vegetation.

Kerr (1852-1888), an explorer of central Africa in Livingstone's footsteps started life as an engineer, working for a period on the old Tay Bridge. In 1873 he went to California in an engineering capacity, eventually rising to the position of acting chief Engineer at the Spring Valley Waterworks. For a period after this he worked on the New York Stock Exchange, leaving there to go to South Africa in 1883.

His one major feat of exploration, described in ‘The Far Interior’, was his expedition from the Cape to the Central African lakes in 1883-85. After a period spent in Southern Mexico investigating sites suitable for colonisation he conceived the idea of an expedition to Khartoum to recover Gordon’s journals. Failing to get permission to enter the Sudan, Kerr decided instead to trek inland from the coast to visit Emin Pasha at Wadelei. He fell ill from fever at the very start of the expedition at the end of 1887 and left Africa to recuperate in the South of France where he died the following year.
