Vintage Blue and White Drip Glaze Sugar Bowl

Beautiful blue and white drip glaze sugar bowl. It is marked "K. ? S. CHINA". It is an unidentifiable makers mark. I believe a USA china company. Mid century styling. Measurements are 4.5" tall with lid. 4" diameter at the top of bowl. It is in great vintage condition. The sugar bowl has no chips, cracks or breaks. The lid has 2 small chips on the neck of the bid, they are not seen when the lid is on the sugar bowl. Please see last few photos.
