The two big axes from below (second one with rings is very heavy) are from the northern part of Nigeria. The third from below (small one with monkey head) should originally be from Chad (acquired in Abuja), the second small is from Nigerian Kaduna State. The axe which is in the top right corner of the picture should be, acc. to
www.spearcollector.com, from Burkina Faso.
