Mustard Yellow Glazed Ceramic Plate with 'Made in Portugal' Mark

The item is the reverse side of a ceramic plate, likely a charger or large serving plate, characterized by its glossy, rich mustard-yellow glaze. The plate features a distinct scalloped or fluted edge, suggesting an organic or decorative design on its obverse side, which is not visible in the image. The glaze appears consistent, without major chips or cracks visible on this side, indicating good overall condition, although minor surface wear might be present that is not discernible at this resolution. The central foot ring is visible, providing stability when placed on a flat surface, and is left unglazed or has a white/off-white glazing. A prominent circular stamp, approximately 1.5 to 2 inches in diameter, is centered on the foot ring. This stamp contains manufacturing details: a stylized motif (possibly a crest or animal emblem, though unclear) at the top, and the text "MADE IN PORTUGAL" below it, indicating its country of origin. Below the text, a small black dot is visible, which could be a quality control mark, a production flaw, or a specific identifier. The craftsmanship appears to be of standard quality for mass-produced ceramic dinnerware, with uniform glazing and no obvious manufacturing defects on the visible surface. While an exact age cannot be determined without further information, the 'MADE IN PORTUGAL' stamp suggests it is a relatively modern piece, likely from the late 20th or early 21st century, consistent with the style of many ceramic items imported from Portugal.
