Extremely rare Hemingray-20 glass insulator featuring a rich green base with black swirls and a scarce matte finish. Unlike typical glossy Hemingray pieces, this insulator has a satin-like surface that deepens its color and gives it a more rugged, industrial appearance.
Front embossed “HEMINGRAY – 20” and reverse marked “MADE IN U.S.A.” with sharp lettering. This dome-top style is highly sought after — especially in unusual colors like this deep green and black swirl combo. The flat finish is not a flaw, but rather a rare result of production variation, adding character and value for collectors.
No cracks or major damage. A premium example of early American utility glass — ideal for display or advanced collecting.
