Exceedingly Rare and Important Three-Gallon Stoneware Jug with Slip-Trailed Cobalt Deer and Floral Motif, Stamped "JOHN YOUNG & CO. / HARRISBURG, PA", circa 1856-1858, cylindrical jug with semi-rounded spout, decorated with a slip-trailed design of a trotting deer with rack above a grassy ground, situated between two differently-styled flowering plant motifs. Cobalt highlights to maker's mark and capacity mark. This jug is one a few deer-decorated stoneware pieces known from Harrisburg, PA, and the only example bearing the rare maker's mark of John Young. Carrying the New York State influence of John Young & Co. potter, Shem Thomas, this jug is regarded as one of the most significant Harrisburg stoneware discoveries of the past several years. Better examples of John Young stoneware feature slip-trailed flowers related to New York State motifs; this example includes two such designs in addition to the extraordinary central deer decoration. Figural motifs from this early, pre-Cowden period in Harrisburg stoneware production are virtually unheard of, with only a few simplistic bird designs known. The discovery of this jug adds insight into the artistic capabilities of the early Harrisburg stoneware makers. Provenance: Recently found in the Shenandoah Valley of Virginia. Base broken and reglued. Otherwise excellent condition.
