Limoges Plate La Porcelaine Limousine

Q: I have a plate marked “PL” with a line under it. The words “Limoges” and “France” are beneath the line. Can you tell me who made the plate and how much it’s worth?

A: The mark on your plate was used by La Porcelaine Limousine of Limoges, France. The company was founded by Joseph Redon and P. Jouhanneaud and his son in about 1905 and was in business until about 1938. A 9 1/2-inch plate decorated with roses made by Porcelaine Limousine auctioned recently for $23.
