NEW UNUSED MINT Union Stoneware Of Maine Blueberry Pattern, Set of 4, CP-41 Large Mugs. GLAZING IS PERFECT AND CHIP FREE. These have a copyright date on bottom of the mugs of 1983 which is close to when we purchased these and other items from the Blueberry pattern when we were in Maine. Union Pottery's website seems to be defunct, and perhaps they are also, too bad, they had wonderful stoneware. These are the larger 15 ounce size of mugs which sold for $21.50 each, expensive, but great mugs. They are 3 1/2"high and 3 1/4" in diameter. These were kept in our china cabinet for display until we packed them up to move 12 years ago; and forgot we even had them. Time to move on. These come from a pet free, smoke free, perfume free household (we have severe allergies). NEW and NEVER USED . I would be pleased to answer any questions. These are heavy mugs and the set weighs just under 3 1/2 pounds. Satisfaction guaranteed or 100% money back. Thank you for looking.
