Mid-Century Modern Hand-Painted Champlevé Enamel on Copper Decorative Plate

This decorative plate is a circular work of art crafted from copper, featuring intricate champlevé enameling. The core substrate is a hammered or incised copper sheet, which provides a dark, metallic bronze-colored ground. The central motif depicts a stylized floral or botanical arrangement utilizing a vibrant palette of forest green, sage, bright orange, marigold yellow, and deep burgundy. Surrounding this central medallion is a wide border composed of alternating geometric chevrons in green and yellow, creating a sunburst or star-like effect. The enamel work exhibits a 'cloisonné-style' appearance where metal ridges separate the colored glass pastes. A distinctive handwritten signature, likely 'Marti' or a similar artist's mark, is visible in the lower right area of the central circle. The piece shows characteristic signs of its age, estimated to be from the mid-20th century (circa 1950s-1970s). Physical condition issues include visible surface oxidation on the exposed metal, particularly around the outer rim and within the incised lines of the border. There appear to be small areas of 'pitting' and micro-scratches on the enamel surface consistent with handling and environmental exposure. The craftsmanship is high, indicative of handcrafted studio pottery or metalwork popular in the Mediterranean or South American mid-century art movements.
