The attribution on this mask, like many objects from Africa, has been complicated by war, migration and resettlement, which have separated indigenous populations who possess similar (or in this case, the same) mask traditions. This mask has been attributed to the Idoma because of its resemblance to two elephant masks first documented by Sieber in 1959 (Sieber 1961: ill. 20, 20a). However, it differs from these two masks in important ways: the supporting structure is different, and this Joss mask has a small human figure carved in high relief on either side of the head. A third distinctive feature of this mask is the use of British West African pennies, one of which is dated 1913, to define the eyes.
