There are no markings on this piece to say for sure, but my research leads me to conclude that this mini mirror is most likely a mid century Murano glass Fratelli Tosi. While many pieces I’m finding online have gold leaf beneath its glass framing, this one has silver tone making it look especially clear. The two (2) floral pieces have a faint pink hue. This piece is old. The metal fasteners are slightly rusty. Please see the pictures. Its wooden backing shows some wear. This cannot be seen once the mirror is mounted. It has a triangle hook. Torciglione refers to the Italian dessert shape of the glass pieces that frame this mirror.
