Société Céramique of Maastricht, Netherlands, was a ceramics manufacturer that existed from 1863 to 1958. This company was later acquired by the Royal Sphinx company of the Netherlands. Olga = means "holy woman / sacred person / blessed." This is a design of dog roses. It seems that wild rose and rose designs were popular at the time, mainly in France and England. It is in very good condition with no cracks or chips. The crazing is very beautiful, and it shows the characteristics of the glaze of this era. I am listing another identical item. Country of manufacture: Netherlands Era: 1930s-1940s Size: Diameter 23.5cm Height 4.5cm Color: Dark green Thank you for viewing. I have come to like the Maastricht designs as well, from French antiques. Compared to the splendor of France, Dutch antiques are durable and the slightly understated designs are easy to use. Please understand that these are antiques, and no claims or returns are accepted.
