What is this?

I have a plain white glazed figurine of a bare-footed girl with flowing hair, dressed in peasant clothing, and raising a three-footed pot above her head to smash down on the fearful figures of a traditionally dressed man and woman beneath her feet. I feel this must be allogorical, but it has no identifying markings. It is 23 cms tall. I would be very grateful for some idea of what it is and when it would have been made. Many thanks.
