Société Céramique pre-1958 Maestricht Sepia Plate Sailboats Ships Holland 13"

I had a kind person send me a message about this piece for reference.  Hi, just politely trying to help, if interested and unaware.The producer's mark on this is Société Céramique, as described, and was used until 1958 when it was acquired by Sphinx and no longer used. SC was a Maastricht company (as was Sphinx) though they used Maestricht, an older word for Maastricht. As such, their art is accurately described as Delft-style, even the sepia.Perhaps this helps a bit for reference.  Société Céramique pre-1958 Maestricht
