Covered pot, ceramic sugar bowl, signed

Adorable little ceramic pot with a beautiful enamel in off-white, turquoise blue and khaki brown tones. It is a beautiful handcrafted work of turning and enameling of which I unfortunately have not managed to identify the author despite the signature underneath, it is up to you to continue the investigation. It can be used as a sugar bowl, a ring holder or to receive a few cotton pads to remove makeup, or simply as a decorative piece with other ceramics. It is in perfect condition, no cracks or chips, just a few slight original defects: small differences in the thickness of the enamel. It measures 9 cm in diameter and approximately 9 cm in height including the lid.
