Lyons, New York 1 Gallon Stoneware Preserve Jar with Large Cobalt Leaf Design. 
Impressed Lyons over two Freehand "1" capacity marks flanking a large dark cobalt leaf and cobalt accents to the handles.
Probably T. Harrington,  1852-1872.
9 3/4" tall.
A couple chips on inside of lip, a very tight hairline on lip and another on the back side. One tiny bubble pop in leaf and a flake on left handle.  All other marks are in the making. 
Great small size!
