Old African Kusu sculpture - Congo Height 22 cm and made in the mid of the 20th century and with Certificate of Authenticity. Origin: Both Republics of Congo & Zambia. About 60,000 Kusu live on the left bank of the Lualaba River. During their exodus from the north, they passed through Luba, Hemba and Songye countries where they assimilated social and artistic traditions of these ethnic groups. They are divided into clans, each led by a chief Wembi, assisted by village heads known as Mwamkana, and by family heads called Bankumi. Historically, the Kusu were hunters, but now they grow corn, yams, beans and raise animals including cows, pigs, goats and chickens.
