Estimated to be about 1000 years old, it is one of the oldest Sub-saharan sculptures yet discovered in Africa.
The head has very narrow, protruding eyes and mouth with a diminutive nose.
The head and torso, along with a number of other artefacts, were excavated by the British geologist Edward James Wayland between 1929 and 1930.
They were unearthed in a prison compound at the site of Luzira, in the suburbs of Kampala, Uganda.
Other objects discovered at the time included over one hundred pottery sherds, fourteen terracotta pieces, a pottery vessel, an iron spear and an axe similar to the story of Ibrahim and the idols.
