An amber half gallon Mason with an embossed Keystone in a circle. An exceptionally fine example in having well-raised embossed lettering, which is the rare exception for this jar in half gallon size. Sparkling clean glass throughout with no damage or stains other than some very minimal ground rim flaking. Comes with a very nice correct original Keystone zinc cap. On the base is "23". A great looking early Mason jar and the finest example.
