Moustier decorative plate signed

Square plate from a luxury craftsmanship, hand-painted in Moustiers-Sainte-Marie. Traditional earthenware from the Verdon Gorges in the south of France. Quite rare. Bird and floral motifs. Signed on the back "atelier des lumières Servanin à Moustier." I can't read the signature of the artisan/painter. Closed French workshop. Classic, old-fashioned and chic style. Adorable, whimsical decor. Barely used, impeccable condition. Fine brushwork on a white background, green, yellow, and orange colors. Made in France. Quality earthenware. Measurements: 18 cm X 18 cm. Height 2 cm. Irregular edge. Authentic by the signature on the back.
