Such containers are a perfect example of making use of what is to hand. The contents of the large egg would be a meal for several people. Then the eggs would be made into an efficient water vessel by attaching a basketry and leather neck with stopper (one missing). They were sometimes buried for use at a later date, perhaps after returning from a hunting expedition. The use of ostrich eggs was widespread in many parts of Africa especially by the Koi-san bushmen of the Kalahari. These containers were traded, as similar examples were collected in the 19th century in Cameroon and in the early 20th in Somalia.
