Final answer:
Materials commonly used for such sculptures in West Africa during that period included metals like bronze or brass, stone, and ivory, indicating the Queen Mother figure from the Kom Kingdom, Cameroon, might have been created using similar materials.
Step-by-step explanation:
The Memorial Figure of Queen Mother in Kom Kingdom, Cameroon, from the mid-19th century does not have specific materials listed in the provided references. However, by examining the materials used in similar artifacts from the region and period, such as the Edo Queen Mother Pendant from the Court of Benin made of ivory, iron, and copper, and Kongo mortuary figures which were carved in stone, it is possible to infer that materials such as metal (probably bronze or brass, given the Benin examples), stone, and ivory could have been used. The referenced figures indicate a high level of craftsmanship and the use of materials that were available and valued within the respective cultures. In the case of the Kom Kingdom, the precise materials would have been chosen for their significance and ability to convey the social status and spiritual importance of the Queen Mother figure.
