Set of 2 vintage egg cups in red earthenware with white polka dots 5cm

These lovely egg cups feature a pretty white polka dot decoration on a red background. In earthenware, they date from the beginning of the 20th century - a service with white polka dots on a red background exists at sarreguemines. In good general condition, I note traces of use and chips on the edge of an egg cup. Dimensions: approximately 4.5 X 5 cm.
