Vintage UCTCI Japan Ceramic Bisque School Girl w/ Book Messenger Bag Planter?

Rare vintage piece, couldn't find another one like this. Happy girl sitting down holding a book bag open. There is some (a little) open space there, wondering if a small plant is meant for the bag? Good condition, one small chip at the bottom of her curl, opposite side of book bag. She measures 7" tall. Vintage UCTCI Japan Ceramic Chalkware School Girl w/ Book Messenger Bag Planter?.
