vintage Maastricht Societe Ceramique pottery bowls, Holland gaudy dutch stick spatter china

Six 5 1/2" diameter bowls, Maastricht ceramic ware, made in Holland.

These have a traditional Dutch folk art style design, we're not sure of their exact age. These look like Petrus Ragout pieces, I think?

All six bowls show some staining and age discoloration, none have chips or cracks.
