This is an adorable vintage, small, shiny penguin pin or brooch. Although hard to see in the photo, it is marked STERLING, right under the stick of the pin mechanism. The pin measures a bit over 1" tall so is perfect for a man's or woman's jacket lapel. It would also be great in a shadow box that would hold a collection of penguin pins. The shadow box becomes a great conversation piece, as well as a neat storage place for your collection!
