Zoomorphic fish ashtray in glazed terracotta

Here is a very original zoomorphic ashtray in glazed ceramic, in the shape of a fish curled up on itself, with lots of details and pretty patterns printed in hollow on the head, scales, fins. I found absolutely nothing similar during my research! A beautiful craftsmanship, which is not signed unless the small circle in hollow underneath is the monogram of the ceramist, circle which is the same size as that of the eye, so signature, sizing test, wink Investigation in progress. It must date from the 60s or 70s. It is in perfect condition, no defects to report. It measures approximately 12 cm in diameter for a maximum height of 5.5 cm.
