The stencilled "Greene Co." is hard to find. The dots under the rim are an unusual touch, as are the 2 stars next to the large 5 at the bottom. There are 2 very deeply incised areas beneath the rim--one below the series of dots and the other below that one. The ears are also decorated. These unusual qualities make this piece very exceptional. In addition, the salt glaze is perfect and there are no burns or flaws of any kind. In fact, this magnificent jar is in mint condition. It was made c1870.
