Vintage red egg cup with white polka dots in Sarreguemines earthenware H6.5cm

This lovely egg cup has a pretty decoration of white polka dots on a red background. In sarreguemines earthenware, it dates from the beginning of the 20th century and is marked "sarreguemines france". This white polka dot service on a red background from sarreguemines is resolutely vintage! In good general condition, I note traces of color wear and two small chips. Dimensions: approximately 4.5 X 6.5 cm in height.
