This is a late 1930s to very early 1940s child's mug or cup by Harker China, also known as Harkerware. The carved dimensional silhouette technique was called Cameo, and in some advertisements, Cameoware. The white under blue design features a soldier on one side, a balancing circus elephant on the other. The 3 inch high mug has crazing and staining (mostly to the solider side) but no chips, flakes, or cracks.
