Ceramic box signed

This beautiful handmade enamelled ceramic box is very original with its pebble shape and its small notch that perfectly fits the lid on the container. The container, on the outer side, is in a pale green tone, while inside it is enamelled mostly in white, the lid is pale green (slightly darker than the container) with in the middle a mixture of dark green and caramel on the outside side, the inside having been left raw, unglazed. It is signed in hollow below, but I will not be able to decipher the signature. It is in good condition, no crack, no stains, just a small shine on the inner edge of the lid, not visible when the lid is placed on the container. The top of the lid has charcoal colored marks, more matte: they are original I think, from the firing of this ceramic. This box measures about 14 cm on one side for a height of about 9.5 cm and weighs about 850g.
