This is an antique A. Lanternier, Limoges cup and saucer set.
This piece dates back to 1900, but Frederic Lanternier started the company in the 1870’s. In 1890 the son, A. Lanternier took over the business, thus the A in the maker’s mark.
This cup & saucer set is in very good, used condition. Take a look at the photos and you will be able to see the dimensions, and get a good look at it. I have two of these available for sale, each individually.
