Technical Observations: The patina is dark brown with bright metal visible. The surface is very well preserved, and there is no etching, corrosion, or evidence of long-term burial. The surface does show evidence of wear.
A depression on the back is the result of casting the object by pouring metal into an open mold. Striations are present from touching up the grooves between the fingers and ribs with an abrasive tool.
