This particular set (5 cups and 5 saucers) appears to be made of fine porcelain and showcases a relief decoration of leaves and flowers around the rim, a hallmark of the Sanssouci line. The absence of gold trim on these demitasse cups and saucers emphasizes the delicate embossed detailing, typical of fine dining ware from the mid-20th century.
Such sets were popular for formal occasions and are sought after by collectors for their timeless elegance and craftsmanship. No damage on any of the pieces.
