Vintage iron/metal? small frog figurine paperweight?

Description

The frog features a green base color. It has rust colored spots in places; as I found it. Some of the brown may be painted on, some may be from aging of the metal or intentional. Again, as found condition. It has wear in the color, inconsistincies in the browns; see all pics and decide for yourself. He looks as if he's been around a while. Measures 2.25" X 1 7/8" X 1.25".
