Huge retro art glass bowl w/ mod asymmetrical spiky shape, Viking Epic line red glass

We love this vintage Viking glass bowl... the rich persimmon red color, the shape kind of like an octopus! It's heavy and quite large, about 8 1/2" square.

There's no label or marking, but it's an Epic line piece (vintage late 60s? early 70s?). It's in excellent condition without damage.
