7 Digoin Mary Lou dark blue edge hollow plates

Set of 7 hollow plates in earthenware by digoin sarreguemines model mary lou painted hand, edge blue overseas, décor of small dark red and deep blue flowers, bluish gray foliage on a creamy white background. Good general condition one with a small halo and another with a small shine on the slice (see photo) imperfections of the enamel and edge with asperities that make the blue on the slice quite irregular, some small scratches of use (probably little used). Beautiful ensemble old probably 1920/1930, they are very bright despite their age.
