Both also appear to have remnants of dried glue or paint to their backs. The larger one is approximately 6" X 4 1/4" X 1 3/8. The only flaw I could find is that one spike of her hair is not glazed as shown in the 7th photo. If this is a repair I don't see any signs of a chip and the color matches beautifully. The smaller one is approximately 5" X 4" X 1 1/8.
The 11th photo shows a tiny dip above her lip that is glazed and original to her manufacture. Please see my other listings for an eclectic assortment of items, both new and vintage.
