Small Stoneware Bowl w/Leaf Lid

Good condition, no chips or cracks that I could find. Two pieces, lid comes off completely. The bottom of the bowl has a black hard plastic or maybe metal flower frog (or similar) glued to the bottom, as shown in photos. 5.25” across at widest point, 4.25” tall w/lid on. There is a signature on bottom of bowl, I can’t read it but have included it in photos.
