To complete a service, here is 1 flat plate and 2 soup plates from the Digoin factory.
Their dimensions are:
20.5 cm in diameter and 4.5 cm in height for the hollow plates
23 cm in diameter and 2.3 cm in height for the flat plate
The Valentin decor (1940s) was painted by hand.
They are in excellent condition but they are not new items so they show traces of use.
The dinner plate is starting to wear a little and has cracks in the enamel on the back.
Details are in the photos that accompany this description.
