Technical Observations: The patina is a pale tan and black crust over a thin green layer. Brown metallic surfaces are visible on the tips of the extremities. The bull is intact, including a tang extending from its proper right front leg.
The bull is a solid cast. It is in poor condition, with loss of surface detail. Removal of the tan and black crust reveals an unusual porous and pitted, pale green, orangish brown, and bare metal surface.
