American Art Pottery porch vase c. 1940. Best guess I think this is Southern Pottery. The numbers on the bottom are probably a shape or glaze number. The base of the vase reminds me of a company that would be attributed to Joe Owens around 1944-1950. However, the handles in the top of vase look like Cole Pottery, possibly AR Cole which would be around 1930-1935. The black glaze was very popular around the 1940's so again makes me think it is likely Southern. The black is a gun metal black glaze. It measures 10 inch's tall. Handle to handle is 8 inch's. Top opening is 4 1/2 inch's. Base is 4 3/4 inch's. I consider the pot to be in excellent condition, please see images. sometimes the numbers on the bottom will indicate are experimental numbers that indicate how long it was fired and what kind of glaze they used.
