This is a decorative Tiki or Aztec/Maya style effigy sculpture, potentially made from materials like recycled volcanic stone, resin, or tree fern trunks. It is inspired by traditional Polynesian or Pre-Columbian designs and often represents deities like Ku, the Hawaiian god of war. The material can vary, but many modern reproductions are made of a mix of crushed stone and resin for durability and weight. It typically features a crouched stance with hands on its head, a common motif in such cultural art. These items are sold as home decor or garden ornaments.
