Another African mystery

Q:  I sent you pictures of a mask a couple months ago… the Bambara mask from Mali.  Thanks for giving me great information.  Here is another of the several I have.  Again, all purchased in the 70’s from a guy in Southern Indiana.  They each appear older… Kevin, 927

A:  The patina on the front and back looks good. Probably African, but hard for me to identify. Let’s hope someone will offer a comment. Here is what I see on the back that might be helpful. It is thinly carved and has 12 holes on the top half of the edge which are probably meant to hold some kind of hairdo. All the other details are obvious.
