Grave statue from Ghana, age unknown, including stand!

Head of a larger statue; a grave statue from Ghana. Varied patina and a good appearance. Having a test that can indicate the age costs a lot of money and is a too big investment to make ...  I cannot determine the age, but the figurine has a low price for a decorative piece. A custom-made metal standard has been made for it, which is of course included.

Length: 14 cm, including standard 24.5 cm
Weight: 704 grams
Origin: Ghana
Date: unknown
Provenance: From a Flemish private collection of many terra cotta pieces
