Hello, this is my first posting. I have recently bought this small cup/bowl at a vide greniere in France and have no idea of the origin. It looks as if it should have a specific use due to the design.
It has a different pattern on the back/front. It has a circular finger handle with a thumb plate over the top of the handle.
Underneath the thumb plate there are some markings which I believe to be a 5 pointed star within a square. There are 5 letters between the points of the star. They look like, starting from top left going clockwise, P E B V M/N. Next to this another square with the numbers 12G in it.
It measures 10 cm internal diameter and 3.5cm tall.
I would be gratefull for any information.
