This is a delicate Shelley China, England side, cake, bread or dessert plate in the Richmond shape in a combo pattern of the variously named Bridal Rose or Rose Spray pattern with a ribbon and laurel leaf border with pink and gold trim.
The pretty side plate was made between 1940-1966 when the pottery closed. I could be more precise if the number was legible, but alas it is not.
The pretty plate measures 6 inches in diameter and is in very good +++ used vintage condition with no chips or cracks and the slightest signs of wear.
A lovely, feminine and pretty pattern which reminds me of lovely wallpaper for your tea table.
