Moore studied the arts of various non-western traditions amongst which masks were not uncommon. During 1928-9 he made eight masks of his own, four in concrete and four carved in stone. In the other concrete masks the facial features are distorted in some way, and they display Moore’s interest in asymmetry. In this work there is little distortion of the features. It is a unique cast and was probably made from a clay original. This assumption arises from the forms of the eye sockets which look as though they were made by pressing a thumb into soft clay.
