Empty pocket cup red burgundy ceramic ashtray

Charming burgundy ceramic pocket or ashtray with charming twisted reliefs enhanced by some golden edging. I have no information about this object but I found some cups with common characteristics (burgundy color and golden edging, twists) that are announced from the 50s and sometimes vallauris. This cup is in good structural condition, neither crack nor shine, but still has traces of its age: a very small chip on the top of the twisted part, some marks, stripes and golden edges are partly faded, erased. It measures 15 cm in diameter, 5.5 cm in height and weighs about 600 g.
