Beautiful Sculpture of a Woman 30 " tall

Vintage 1983 Austin Productions Statue, Inspired by Eugene Marioton’s “La Grace.” Measures 30” tall, weighs 32.4 lbs, and is signed and dated on the base. I’m uncertain about the material of this sculpture. When tapped, it sounds hollow, though some sources indicate it could be made of bronze or white spelter. I haven’t been able to verify this.
