This is an ashtray shaped like a Tiki head with a large open mouth. Unlike most ashtrays that lay flat, this one sits upright like a bookend and has a deep mouth. It was produced in a variety of colors. Many are produced in a "lava black" or "sandstone red" and appear to be carved, however, this is definitely a molded piece. Not ceramic, but chalk or composite material. Probably manufactured in 1970s, but not certain.
