Thanks for stopping in to see this wonderful piece of pottery. The inside of the vase itself has a glossy waterproof glaze for use, while the outside is matte with natural color disparity in a linear vertical pattern. Along the bottom rim is a simple 6 and unfortunately no makers mark that is legible or present to me so I don't know if it was a sticker by Teco or just not signed so I really tried to get alot of closeups. Please I hope you can see all 23 photos so you know just the exact age, use, size, look and feel of this vase from every angle. Let me know of any questions at all!
