Sturdy and unique circular container/locket with MOP embellishment on the top is featured. The box is suspended from a chain which measures 24 inches long. The locket itself measures 1 3/4 inches in diameter and 1/2 inch high. The box springs open when a button is depressed on the side of it; inside is a piece of paper with a doctor's name and number. I left it in there because it is like finding a locket with pictures; it only adds to the interest and provenance. This is in wonderful condition; it is unsigned. The chain is not brass.
