This is a French Haviland & Co hard paste porcelain platter or tray. The date is the 19th century, circa 1876 to 1889.
The tray is 9 ¼” long by 7 ½” wide.
The glaze on the rim is what the author Nora Travis describes as “turquoise” in her book “Haviland China The Age of Elegance.” The color appears to be teal to me, not turquoise.
The pattern is one designed by Dammouse, hired by Haviland specifically to create patterns to appeal to the high market buyers of Haviland china. You can see this pattern in the book on pages 28 and 29.
The pattern has a lot of gold in it. The pattern is one of flowers on long stems: green, red and gold. There are lighter shades for a background effect.
The gold overlay around the center of the tray is worn. The gold trim around the edge shows age wear. There is one small nick on one edge.
The green underglaze mark is H&Co over L. The red overglaze factory decorating mark is Haviland & Co Limoges.
There is a sticker on the back with a handwritten note telling how the tray was handed down in one family to successive generations.
There are no other chips, nicks or cracks.
