I understand from one source that this woman is meant to represent Queen Louise of Prussia--and I've found this was a pretty popular portrait, which appeared in on boxes and mirror backs and dishes, too, and this one definitely once had a frame of some sort around it. I just love the star at the center of her head piece, turning her into a sort of Victorian era wonder woman! 

The reside around the edge of the porcelain scrapes off pretty easily should one want to clean this up a bit, but I can of like to combination of that and the crazing, counterpointing her prettiness a bit. 3 1/2" x 2 5/8" x 1/4".
