Late 19th century Gien earthenware dish/soup plate

Very rare small dish decorated with sponge overpainted with pink flowers (diameter 26 cm, depth 4.5 cm) - or large soup plate - from the Gien earthenware factory, signature stamp from the 1880s/1890s. In very good condition on the front, shiny enamel, not cracked, not cracked, no wear except for its age. On the back, very infiltrated cracks, brown appearance but intact surface. Lots of charm, unique.
