Circa 1875: Measuring almost 10" tall, this one gallon Southwestern Pennsylvania storage jar manufactured for Pittsburgh's well known Diamond Market district merchants W.D. Cooper & Bro. remains in superlative condition with only the most minor of wear on the inside lip and no chips, cracks or repairs. The dark blue cobalt stenciling and top and bottom freehand stripes contrast beautifully with the jar's desirable gray surface, making this a vibrant, simple, and tasteful example of 19th century PA blue and gray stoneware.
