Historical Bas-Relief Cameo Glass Plate

This appears to be a decorative commemorative plate, likely crafted from a type of white or opalescent glass, possibly 'milk glass' or a similar pressed glass with a cameo-like bas-relief design. The plate features a central scene depicting three figures, two seated at a table and one standing beside them, engaged in what appears to be a historical or allegorical gathering. The central figures are rendered in prominent relief, suggesting a well-defined mold was used for its creation. The edges of the plate are adorned with a continuous rope or braided motif, adding a textural and elegant border. The overall color is a pale, milky white, consistent with opaque glass forms. The plate is presented within what seems to be its original fitted dark blue, possibly velvet-lined, presentation box, which suggests it was intended as a gift or collector's item and indicates a degree of care in its packaging and preservation. The condition appears to be excellent, with no visible chips, cracks, or significant wear. There is no discernible maker's mark or signature clearly visible in the image, though such markings are often found on the reverse side of such plates. The style and historical subject matter suggest it could be a mid-20th century piece, perhaps commemorating a significant American historical event or figure, given the apparent style of dress. The craftsmanship appears to be of good quality, with clear detailing in the relief work. The handmade glass context suggests a carefully made piece, potentially from a limited production run.
