A photojournalist based in East Africa since 1991, Gilbert (Broken Spears) turns her attention on the traditional peoples of Eritrea, the Ethiopian highlands, and plains of Kenya, Tanzania, and Malawi in this collection of striking black-and-white photographs. She includes Maasai and Samburu warriors, the Mursi with their jutting lip-plates, the guinea-fowl-painted faces of the Karo, the bull jumpers of the Hamar, and the honey seekers of the forests, the Batwa, among many other groups.  (EAF180, $75.00)
