Vintage 1930s Rosenthal Dish

Vintage porcelain ashtray. I say ashtray but I’m only guessing from the logo on it (cockerel with pipe), maybe for pipes as it’s uncharacteristically thick and chunky. I presume it’s either advertising or from a bar/restaurant. Made by one of Germany's best known porcelain manufacturers Rosenthal. The backstamp dates this dish to 1937. Made in Germany from glazed porcelain. 14 x 14 x H4.5cm Please note: These are vintage items so will show small signs of use. There are no chips or cracks, just some minor scratches on the inside.
