Croesus Tumbler Imperial Emerald (green with worn gold) Non-flint. Riverside Glass Works, Wellsburg, WV. Late 1897. The glass is a gorgeous deep green and any colors you see in the photographs are reflections from indoors where I photographed the piece. There are lovely bubbles, straw marks, and glass is wavy, four-part mold. Color and clarity are very nice. Gold is very worn on the tumbler.
