Cobalt Decorated Stoneware Advertising Jug

This nicely decorated jug was used to advertise for P. S. Proctor's business that was located on the corner of Jefferson & Lowe Street, Lowell. I do not know the state where this jug was used. This two gallon jug is from the second half of the 19th century and is in excellent condition. H: 14", Diameter: 9".
