Old olive green oval serving dish Gien France

Very rare model for this old serving dish, great ceramic delight of the mythical house gien. A deep olive green enamel with subtle shades of hue a bit like a painting, a monochrome. The perimeter is decorated with simple touches of paintings. A marvel, we especially love its very rare color, the subtlety of the email and its shape. Very good condition, note the traces of wear due to time. Signed gien france on the bottom.
