Rare Two-Gallon Stoneware Jar, Stamped "MANUFACTURED BY J. CRUMBAUGH.", Indianapolis, IN, mid 1820's, ovoid jar with heavily-tooled shoulder, arched tab handles, and thin, semi-rounded rim, impressed at the shoulder with Jacob R. Crumbaugh maker's mark above a three-gallon capacity mark. Underside impressed "SO". According to Mark C. Wiseman's article on Crumbaugh in the July-August 2015 issue of Bottles and Extras, the potter worked first--beginning in 1823--as the master potter of Margaret Gibson's stoneware manufactory on the corner of Ohio and Tennessee Streets in downtown Indianapolis; a few years later, Crumbaugh struck out on his own at the corner of Kentucky Avenue and Washington Street, but there is no reference to his establishment beyond the year of 1826. A rare example of Midwestern stoneware. Heavy chipping to handles. Y-shaped crack in underside, part of which continues approximately 8" up front of jar. Rim chips. A few firing flaws to surface.
