This is a vintage ceramic Japanese girl piggy bank.
The black haired girl is wearing a hand painted blue, green, and yellow kimono and tucked under her left arm is what appears to be either a pillow or bag of rice.
This piggy bank measures 6" tall and 2.75" wide. On the bottom is the number 645 in black ink.
It is in good pre-owned condition but does not have the bottom stopper/ plug.
