Vintage Large Art Glass Bowl Dish Vibrant Multicolor Rainbow Swirl 13 Murano

Spectacular large art glass bowl with vibrant primary-colored swirl pattern layered over milk white and banded around the edge with black. Measures 13" in diameter and 2-1/2" tall.

No damage of any kind, but there are very fine scratches on the base that make me think this is older. Has the feel and appearance under close examination of 1960s or 70s to me, but may be more contemporary? Honestly, the one thing I do know is that it is fabulous!!
