Beautiful, Vintage Four Horses Running Pin Brooch

This is a beautiful, understated pin/brooch. It is only two inches (2") in length, so it is not big or heavy. The material is not known. It is silver-like or pewter-like. There is no specific imprint I could find. Though small, it conveys the vigor and energy of four horses running side by side. It was a gift more than twenty years ago to my mother, who had a deep passion for horses. Bundle this with two or more other items from this closet, get a discount, AND save on shipping! From a non-smoking, critterless, unscented household.
