There is a line in the underside of the bowl. It doesn't seem to be a crack. It looks to be just part of the bowl.
The pattern on the different cups appear to be of a different pattern as well. Bowl edge is scalloped, ribbed and serrated, the cut pattern is English hobnail, and spinners in a swirl form bottom to top, and coordinated with the base swirl. 12" wide, 5.5" tall. The interior base is 4 wide. The cups are 3" wide and 2.5" tall, and the other cups are 2" tall x 3.25" wide.Thank you for looking at my items.
