Technical Observations: The patina is a smooth black with light and reddish-brown corrosion. No red cuprite is evident, and the reddish brown that is visible may result from iron. There are casting flaws, patches, and rough tool marks on the reverse.
The figure is hollow, although it was cast with thick walls that make it very heavy. There are plugs in some of the casting flaws. The object has a cement-like core material and accretions. The surface shows tool marks from cold working done for finishing, but major casting flaws were not filled.
