Art Deco Style Pewter Dish with Geometric and Abstract Design

This item is a square-shaped, shallow dish crafted from a dark, possibly aged or patinated metal, likely pewter due to its color and matte finish. The dish features a smooth, unadorned central basin with straight sides and slightly rounded corners. The most striking characteristic is the wide, flat rim that surrounds the central depression. This rim is intricately decorated with a repetitive, debossed or engraved pattern that suggests an Art Deco or possibly a tribal/abstract aesthetic. The pattern consists of a series of symmetrical motifs, including teardrop or eye-like shapes, crescents, and small circular dots, arranged in a continuous band around the perimeter. The design elements are recessed and appear darker than the raised surfaces, enhancing the contrast and visual depth. The corners of the rim curve gracefully, maintaining the continuity of the pattern. The overall color is a uniform dark gray to charcoal, with a subtle metallic sheen. There are no obvious signs of significant damage like dents or cracks, but the surface of the basin shows minor scuffs and marks consistent with age and use, indicative of a natural patina rather than severe wear. No manufacturer's marks, signatures, or stamps are visible from the provided image. The craftsmanship appears to be of good quality, with precise detailing in the decorative elements and a sturdy construction. Its estimated age, based on the design cues, is likely mid-20th century, possibly earlier if it leans more into Art Deco influences.
