The Crestview Collection Willow Medium Two-toned Sculptural Leaf I is made from aluminum and has a silver finish on one side of the leaf and a bright brass finish on the other side. The leaf is curled just enough to allow you to see both the brass and silver finish of the sculpture when displayed. The artist has detailed the leaf sculpture with a stem, a vein running through the middle of the leaf, and the smaller veins sectioning off each part, almost as if a real leaf had been dipped in metal.
