Large Blue Cylindrical Optic Vase by Blenko

This 1980s Blenko blown-glass vase is large in scale and vibrant in color. Extraordinary ‘optic’ texture with a subtle linear pattern throughout.
Unsigned / labeled, but pontil on bottom is crude (indicative of hand-blown glass, as opposed to mold blown, and commonly associated with Blenko’s works).

H: 15″ x Diameter: 6″
