Large African Wall Plaque

A beautiful and fairly large (19" X 19 1/4") carved African wall plaque, made from a slice of a tree stump. It features three men, a chief or king in the center with an armed warrior and an advisor at his sides. The background looks to be structures topped with palms. To me it looks Kenyan but google suggests that its Yoruba (there are similarities but not a match). It is an inch deep and please check the pictures for wear.
