Aztec Calendar Decorative Brass and Enamel Souvenir Plate

This is a circular decorative souvenir plate featuring the Aztec Calendar (Piedra del Sol/Sun Stone) as the central motif. Constructed from a polished metal, likely brass or a brass-plated base, it showcases vibrant kiln-fired or cold-enamel polychrome work in shades of emerald green, deep red, turquoise blue, and white. The plate is divided into distinct registers: a central medallion depicting the sun god Tonatiuh, followed by concentric rings containing various Nahuatl glyphs and symbols representing the 20 days of the Aztec month. The wide outer rim is finished in a saturated green enamel and decorated with stylized eagle and serpent figures, reflecting Pre-Columbian iconography. At the bottom of the rim, the word 'MEXICO' is prominently integrated into the design. The plate exhibits a high-gloss finish typical of mid-to-late 20th-century tourist ware. The craftsmanship indicates a commercial production intended for the gift and souvenir market, likely dating from the 1970s to the early 1990s. The surface appears to be in relatively good condition with no visible chipping to the enamel, though minor surface scratches and slight tarnishing on the exposed metallic segments are consistent with its age and use as a display piece.
