5 mary lou digoin blue edge hollow plates

Set of 5 hollow plates made of earthenware of digoin sarreguemines model mary lou painted hand, blue edge décor of small dark red and deep blue flowers, bluish grey foliage on a creamy white background. Very good general condition one with a small shine on the slice (see photo) a lot of imperfections of enamel inside and outside (see detail) and edge with asperities that make the blue on the slice quite irregular, some rare small scratches use (the majority have not been used). Beautiful old set probably 1920/1930, they are very bright.
