This is a D-handle mug from the popular "Fire-King" series by the American company Anchor Hocking, in the popular Jadeite color. The bottom stamp "OVEN Fire-King WARE MADE IN U.S.A." indicates it was made in the 1956-1960s, making it an original piece from that era. Size: Approximately 8.5cm tall Condition: No cracks or chips, glossy and in good condition. There are slight variations and small air bubbles from the manufacturing process. The thick, milky green color is beautiful, and it evokes the atmosphere of an American diner. Recommended for collectors and cafe interiors.
