Standing Four-Armed Avalokiteshvara Flanked by Tara and Bhrikuti(?)

The image shows a bronze sculpture of three figures. The central figure is a four-armed male standing on a lotus base; he wears a long dhoti and a tall crown. His right arm is bent at the elbow, and his left arm is extended downward; he holds an object in his upper right hand. A large, pointed oval halo surrounds him. The two smaller figures on either side are seated on lotus bases; both wear a crown and have their hands in their lap. They are surrounded by a pointed oval halo. All three figures have a green patina and appear to be made of bronze. The background is a gradient from dark brown at the top to light brown at the bottom.
