Vintage ceramic vase signed vague - Green glazed terracotta

This superb vintage vase is made of glazed ceramic. It dates from the mid-20th century. Flared in shape and tightened by an annular collar, it is decorated with an irregular covering of a pretty green. It is a terracotta, we find the modeling lines and the enamel is velvety. This vase is signed at the wave pontil and from one point, I cannot identify the signature. In very good condition, it measures approximately 13 cm X 18 cm in height. I point out some white marks, scratches on the sides.
