Chef Bamoun From Cameroon Bronze

Rare representation of a Bamoun Chief with his prestigious headdress encrusted with cowrie shells bronze character covered with abrus (red seeds) His right hand is in the form of a megaphone, his mouth open seeming to scream and his left hand holding a scepter There is a lack at the top of the right arm (accident, casting defect or desire to ventilate the container or other?) otherwise very good condition I do not know the use of this sculpture which seemed to serve as a container with a prominence on the belly serving either as a pouring spout or to receive a tube like a pipe or musical instrument? This is the first time I have seen a sculpture of this type despite my fairly extensive documentation (more than a thousand books on primitive art) but I do not have them all The provenance of this piece is that of the collection of Maurice NICAUD 1911-2003 who was an indisputable great connoisseur free shipping worldwide
