Vintage Cobalt Blue Canning Jar - Very Large

Up for bid is this very large cobalt blue jar. This was found at an estate sale, so I don't know the history, but I found the unusual shape to be very intriguing, sort of reminds me of a light bulb. It has several markings on the sides that may not come through in the photos, but I wish the pictures could show how impressive this piece really is. On the front is "Grandma's Brand All Storage Jar Preserving", and baking/cooking implements. On the back it says "5 lbs. Warranteed Measure". On the bottom is "CGC 1982". All of these markings are raised, not stamped or painted. The jar is 9 1/2" tall and 8" wide at the widest. T is a rubber seal canning lid to close the jar. This jar weighs over 4 pounds. If you have any questions, please email me. Thanks for your interest. I accept Paypal only for payment
