Warning: This article contains an image which readers may find distressing.The black-and-white photograph shows a man, perched on the edge of a wooden deck, looking down at two objects. At first, you can't take in what they are.
In the background are palm trees. Two other men stare grimly at their friend or perhaps the photographer, it's hard to tell.
The photo was taken in 1904 at a missionary outpost in Baringa, in what was then called the Congo Free State. The man's name was Nsala and his wife and children had just been killed.
Alice Seeley Harris's photograph of Nsala, looking at his five-year-old daughter Boali's severed hand and foot caused an uproar back in Europe.
