I have an Italian Glass swirl canes bottle/ decanter with top attributed to Gio Ponti mid-century 1950's. It subtly and elegantly combines the very beautiful colors Royal/Colbalt blue and red that intermingle to give a geometric and very decorative aspect to the piece. Unmarked. With Pontil.
It is in very good condition with no chips or cracks, just a couple of small surface scratches at the bottom.
Measurement:
with topper, height 9 1/2 in
