Turquoise and purple tray evoking an oyster - Art Nouveau - late 19th

Large dish or tray, turquoise border with art nouveau scrolls, purple background in the shape of an oyster. Could be used as an inkwell tray. This pottery with a very assertive patina is ideal to bring a touch of old and authentic in an interior, its pastel colors and its marine theme blend perfectly with the feminine universes, seaside interiors, fairy, bohemian, mermaid, art nouveau and frenchy. No signature. 32 cm long. 21 cm wide. 3.5 cm high. 756 g in total. Very patinated: the tray bears many old splinters softened and marked by time, the object is not intact but its "defects" are very aesthetic and the overall structure remains very solid.
