These snuff containers (items 1a and 1b) exemplify the aesthetic sensibility that characterises south-east African material culture. In this example, the torso resembles a human with elongated arms yet the face has baboon-like features.
Examples of more figurative horn snuff containers can be seen in M Shaw, 'Some native snuff-boxes in the South African Museum', Annals of the SA Museum, XXIV, part III(7), 1935, plate XXIX.
