Small cup and saucer commemorating the German palace at Sanssouci in Potsdam.  Mark reads TK Burgwindheim, which I believe is Theo Kuhn. I did try and research the mark and the only thing I found said date might be around 1970. Very good condition, cup is just 2 1/2 inches in diameter. Saucer is 4 3/4 inches. No cracks or chips.

Feel free to email with questions. Have a great day!
