This is a vintage Zanesville 1960s stoneware style #4012 pot/planter/vase. It was part of the "Stone Age Modern" line. It measures 12 inches tall and 6 inches wide. It has a small chip on the top lip that circled in the last photo.
This product would be a great fit for those looking for a modern-style vase or planter in an antique finish, which can add a unique and charming touch to any home or office decor.
