Black ceramic and foam shell ashtray

Very beautiful ceramic shell-shaped ashtray with a magnificent black glaze decorated with a white "foam". It is pleasant to look at but also very satisfying to the touch, the foam providing a very light texture. It could also be used as a pocket emptier for small office supplies, a soap dish or an original coin tray. It probably dates from the 60s or 70s. It is in perfect condition, no cracks, no chips, not even a chip. It measures 18 cm in length, approximately 13 cm in greatest width, approximately 5.5 cm in maximum height.
