Reproduction Cobalt Blue Mason's 1858 Half Gallon
I'm not a jar expert but I'm pretty certain this is a repro jar. Even so, it adds great color on the jar shelf. Large half gallon size.
Embossed: MASON'S / PATENT / NOV 30TH / 1858 // (Maltese cross)
Color: cobalt blue
Condition: near mint - structurally perfect. Just some spotty light wear and a haze patch to clean up.
