This porcelain coffee cup in the "London" shape has beautiful painting in cobalt and gilt.
No maker's mark; painted numbers probably indicate shape/pattern. Very likely by Ridgway ca. 1815, as a similar example is shown in Berthoud.
Size: Top diameter approximately 2.875", 2.5" high.
Condition: No chips, cracks or repairs.
Note that I try to be conservative about condition descriptions, carefully noting any flaws. Of course, with antique items, there will be some signs of usage, and/or manufacturing defects. But overall, my customers have always been pleasantly surprised upon receiving their items, and of course, Returns are no problem if I happen to miss anything.
