Large blue slag hen on nest

This big and beautiful covered animal (Hen on a nest) dish is such a lovely color. Slight variations of cornflower blue milk glass slag. Just a hint here and there of a chocolate coloring through the glass. 7" tall and about 8 1/2" long. Very well made, lid fits nicely. No rough irregular edges. Pristine condition. Nicely detailed face and feathers. However there is no makers mark that I can find! You would not be dissapointed, she is so grand! Not sure of year of production.Email for more photos.
