Monumental Ten-Gallon Stoneware Jug-Form Water Cooler with Freehand Cobalt Decoration, attributed to James Hamilton, Greensboro, PA, circa 1865, ovoid, jug-form cooler with circular bunghole, two finely-extruded handles, and tooled banding around the upper half, decorated at the shoulder with a large undulating vine above a wavy freehand stripe. Further decorated with a freehand "10," flanked by wavy stripes and underscored by a long wavy stripe. Cobalt highlights to bunghole and handle terminals. Similarities between the decoration on this cooler (including the penmanship of the "10") and the hand-signed, ten-gallon "Day & Ross" jar in Crocker Farm's Spring 2020 lead to a firm attribution to James Hamilton. Rare form, exceptional size, and superb color, made by one of the region's most important potters. Provenance: A recently-surfaced example, acquired by the consignor in Maryland. A Y-shaped crack on underside, extending up reverse to shoulder. A shallow 1" chip to top of spout. H 22".
