Antique "Keramis" Cream Crackle Glaze Art Pottery Help!

I recently picked this up at a local thrift store mainly because of its unique style. I got it home and tried to get some information about it on the net...and have been unable to find ANYTHING even similar to it anywhere. Lots of Boche Freres/Keramis Art Deco pottery online, all of which is painted in Art Deco Era Styles and Bold Colors. Can find absolutely nothing that is not brightly painted nor can I find any style similar to this...Any help would be greatly appreciated...

Height: 11 3/4"    Diameter at widest point in middle: 23"  Rim: 1 1/2" diam. Base: 3 1/4" Diam.

There are 4 "handles" at the top, and it has a small hole in the bottom, which would prevent it from holding any liquids. It has a couple of minor age spots near the top,and bears the "Keramis" Black mark stamped on the bottom (a bit smeared though) Some crazing is evident over much of the piece.

I am interested in anyu information about it's age, creator and current retail value?

Thanks!

Good
