Decorazione Artistice
These are mechanically made glasses with an acid stain colouring and mechanical (?) cut pattern. They may be from Naples, they may be from Empoli or they may be from Bormioli in Parma - I suspect the latter. It is not crystal, it is glass. It is not from Murano. It is from the 1950s or 60s - and they are definitely wanting in quality.
This type of glass was popular as wedding presents just after the war - if you have any of that in the family, you have a date :-)
