HISTORY/MARKS: Paul Maurice Mavaleix worked with Henri Balleroy and Mandavy from 1901-1908. The PM de M mark is frequently misread as BM de M due to the script used. In Mary Frank Gaston’s Collector’s Encyclopedia of Limoges Porcelain, 3rd edition, this mark on this plate is mark #1 and was used 1908-1914.
