Porcelain saucer, made in what was at the time part of Germany, now Poland. Maker's mark on underside. Collected in Sundborn, Sweden.
Maker's mark on base refers to Tielsch, C. & Co. porcelain manufacturers, who were based in Altwasser, Silesia (called Stary Zdrój after 1945), an area which is now a part of Wałbrzych, Poland. This mark was only used by the company between 1875 and 1934.
