The imprint of the Gerber baby did not go as planed the imprint resembled a cute black baby hair and face features, These were never circulated and then error was corrected as you will see in my pictures of the correct imprinted mason jar mug. It holds approx 16 oz. NOTE THE LAST 2 photos are of the corrected baby Mug.Found some info on it but I do not see Mason or Ball imprinted on this jar.
