Ditmar Urbach Czech Art Deco Alienware Pottery Vase 1920s Or 1930s 6.5" Crackle

Cool Alienware pottery vase by Ditmar Urbach in Czechoslovakia. No chips or cracks. It has some areas where the glaze didn't adhere, but that's part of the design. Numbered on the bottom, but I'm not sure what it says. Possibly 8107. Brown and cream crackle glaze with black details. Some of them look like fish. It measures 6.5 inches wide, and 6.5 inches tall approximately. Some felt on the bottom, could be removed.
