The collection, assembled by the rare book dealers Jenny Allsworth and Humphrey Winterton, brings together photographs, photograph albums, glass lantern slides, and a lantern projector, which document the Sultanate of Zanzibar and European colonial expansion in East and Central Africa from 1870 to 1914. Also documented are early Arab and Portuguese coastal settlements at Kilwa, Mafia, Pemba, Sofala, and Zanzibar and the work of photographers who operated in different parts of the region.
