Unlike metal weathervanes, which have been commercially produced from molds since the mid-nineteenth century, most whirligigs continue to be handmade and often express the interests and ingenuity of their makers. The most basic whirligig type is a single figure with either paddle arms or a propeller. This whirligig is simple in construction, comprising a brightly painted elemental figure with a propeller at the front. Its interest is derived primarily from the unusual imagery of a witch riding a broomstick, the witch appearing to fly around when the propeller is turned by the wind. Although mythological images were not uncommon in weathervanes, witches were infrequent subjects of American folk art in any medium.
