Small, decorated porcelain vase. From where and when ?

Many years ago I inherited this only 9 cm high, decorated porcelain vase. It's too small to be of much practical use, so it must mainly have been made for decoration and I find it decorative too. The design is obviously inspired by Greek vases from Antiquity, whereas the 'Fleur de Lis' decoration comes from France. So it's definitely a European vase. No marks on the bottom or elsewhere. I know for a fact that it's not younger than the middle of the 20th century. Maybe you can tell me where it comes from and when ?
