The Yohure Mask is made and used by the African tribe, the Yohure who are located in the central region of the modern day Ivory Coast. Yohure masks combine the features of a person with the features of an animal. However, they almost always contain certain features such as horns, elongated faces, and a low protruding mouth. They also are usually outlined with a triangular zigzag pattern.
