Rare Vintage Child's Cup Hand Painted Milk Glass

Very rare child’s cup. Vintage milk glass with double handles, front painted with a rabbitt, dog, and ball. Painting in excellent condition. The inside of cup you can with fingernail feel a flaw in the glass. I cannot see a crack or feel any crack with pad of finger so may be a design flaw in the glass making. It is in excellent condition for this very old and rare vintage cup.
