Vintage fish tureen cookie jar

Vintage terrain and quality condition has never been used by me. It was passed down to me Super vintage looking lovely fish container terrine you name it you decide! 15 inches long with a mouth opening on top that is 6 1/2 inches I’m not sure what year this was made or much about it. I purchased it and loved it but never used it. Just kept it in very good condition. Used for display.
