Circa late 1960's, early 70's. 2 1/2". Medium concentric. 37 canes. Center raised to form bouquet like design. Colors of red, yellow, pink, greens and blues. Clear base with inward center.
This was given to me many years ago (1980's) with an estate auction tag that read Perthshire, 1960's. I have my doubts about that. It is more than likely an early Murano or American. My husband named it "Flower Power" many years ago.
