This charm is so delightful with it's scalloped edge and lovely design on the top. When open thee is a fixed puff and mirror. Possibly a "Terranova " charm but since the powder puff is secured and I don't want to try to remove it to see the makers marks. The back has a smooth center and is marked sterling. Measures 1/2 Inch diameter. The condition is excellent vintage. This petite charm has it all.
