Ceramic Tribal Wall Mask by Raylin

A large ceramic wall mask made by an artist named Raylin in 1979. I am not sure what it depicts as to my eyes it could be anything from a soldier in a helmet with a nose guard to a woman in ceremonial head gear to someone in traditional costume. The mask's face is decorated with what look like rivets and stars. It is 10 3/4" long by 8 1/4" wide by 5" deep.
