I purchased this over 20 years ago at a department store and have kept it stored in the closet at home (still in the box). The bottom of the cup (image 12) has turned slightly brown with age, but I couldn't remove it even after wiping (last image). There is no box. I will also be listing a pair of cups and saucers from the same series, so please consider them as well. - Design: Sugar pot with floral patterns and gold decoration - Material: Porcelain - Shape: Round, with lid Thank you for looking.
