Does anyone know?

I just fell in love with this Lenox piece when I found it. It is small at only 7 3/8" tall to the top of the lid and 4 1/2" wide including the handle. It had a tiny chip on the lid but I didn't care because it was different than any Lenox I had ever seen. I have searched the internet until I am crosseyed, :-), but can not find anything like it. It almost has a marbled like finish and it may be a design but I haven't been able to make that out. Do any of you Lenox lovers out there know what era this is from and what the style is called? I would also be interested in finding out an approximate value as well. I know the chip takes away from it but I like knowing what kind of "Deal" I got. LOL! Thanks so much in advance!
