A collection of photographs on 77 loose sheets. On one sheet, in ink capitals, is written 'Photographs taken between June 18th 1934 - December 1934, in the Lamu Archipelago, Tanganyika, Kenya, Uganda, Belgian Congo, Ruanda Urundi, French Equatorial Africa, Cameroons, Nigeria, French West Africa.' The majority of the photographs have been captioned by hand, in a difficult handwriting, and some of the names of peoples and places have not been traced in works of reference. The following guide to places is arranged in the order of Powell's account quoted above (with the addition of Sudan, clearly part of the same journey) but can only be regarded as a rough indication of contents as some of Powell's own captions indicate otherwise.
