Rather than from the Lega themselves, this mask may be from one of the many groups influenced by Lega art, perhaps from the Nyindu or another group to the south-east of the Lega proper. Amongst the Lega each member of the yananio grade owned a wooden mask for use in the lukwakongo rites leading to membership in lutumbo lwa yananio (see Biebuyck, 1973, e.g. Pl.62)
