MCM / Mid Century Italian / Venetian Art Glass Bowl.
 The  bowl features  a stunning combination of blue, green and amber cased glass, using the renowned Venetian Sommerso technique.

This bowls displays beautifully  however there are surfaces scratches on the bottom, a (smooth)chip at the edge on the bottom and in at least three areas small tiny nicks on the sides. One such area has a scratch in addition to the nick.
