FLOW BLUE COVERED VEGETABLE DISH;CANTERBURY PATTERN

This is a very old covered vegetable dish that is marked on the bottom:Royal Semi Porcelain Canterbury Pattern Booths England.I know very little about flow blue,but I'm sure its quite old.I can find no chips or cracks except for some dark markings that look like air bubbles that popped during firing.Shipping cost is determined by your zip code.I'm posting a couple other pieces,and I gladly combine shipping.
