This is an Unsigned piece with a stamped leafy plaque and filigree back plate. I've had the matching pendant necklace marked Miriam Haskell. Beautifully enameled green cab can also be found in blue from this design line. Measures 4.25 inches by 3.5 inches. The enameled cab is 1.5 inches. Some oxidation to the goldwashed brass leaving this piece with an authentic, warm and rich patina. No verdigris. A substantial piece that wears beautifully!
