For you from Italy, I have this very unique silver oval with the Goddess Meditrina. She was a Roman goddess of health-longevity and wine. This treasure is available at my Zen Cart powered on line boutique Mariette's Back to Basics, see link below post.
This beauty has a lacquered wooden back and comes with acrylic-easel; it will not tarnish!
BN is from the province of Benevento, Italy.
Ag means Argento (silver)
