This vintage 1910-1923 BALL MASON blue-glass quart fruit/canning jar is in good condition.  One side of the jar is embossed with the words Ball MASON.  The mold number 3-2 is embossed on the base.  The jar is approximately 6 3/4" tall.  As expected with vintage canning jars, there are manufacturing flaws including big bubbles in the glass.  The jar shows very little wear consistent with its age and purpose including the rim wear and bottom surface wear
