This is a mid-century modern ribbed cylinder vase from the Zanesville Stoneware Company (often referred to simply as Zanesville Pottery) based in Ohio.
This specific design belongs to their highly collectible "Homespun" or "Stoneage Modern" line produced between the 1940s and 1960s. The piece features a characteristic raw, horizontal ribbed texture covered in a semi-matte white or light cream glaze that allows the natural tan stoneware color to subtly peak through the ridges.
This piece is stamped #4008 which indicates it's the 8 inch model.
