Early matte green art pottery vase. It is green, see picture 4 of it next to a matte aqua vase, and pic #8. Hand formed; has ridges on interior. Might be early Roseville or Pewabic, have not had time to check any books yet. I am in MI so Pewabic is more probable. No chips or cracks; has some stray blackish marks on the exterior which is quite common on matte pottery. It is just a bit over 6 inches tall x 5 wide at top. Very nice piece of Arts & Crafts pottery. 2/11ro#3502
