Vintage Folk Art Pig made of Galvanized Steel circa 1930 - 1940

Life size folk art head of a pig fashioned from galvanized steel.  Galvanized steel began being used in Farms around the 1930s, and since the material was designed not to rust, yet this piggy has, I'm going to guess it was an early make-do use.  More common are figures like the tin-man...I am even going to guess this was utilitarian, and made to be mounted on a building raising hogs.
