Why do you think it is anyone in particular ?? Can you read at least part of the words/letters on the lower mark ?? That line is blurred !! Can you post a pic of the item with the mark on it ?? Just because the backstamp says Limoges, France,, that does not necessarily mean it was decorated there !! Many pieces were bought as blanks by other decorating studios as well as exported to the U.S. and decorated by amateurs !!
