5 vintage mid-century stoneware mugs (3 Northcraft, 2 Made in Korea)

Set of 3 vintage mid-century Northcraft Korea stoneware mugs. One mug has a tiny lighter coloured spot in the glaze on one side, which would have happened during manufacturing. These highly collectable mugs do not appear to have been used and are in excellent vintage condition. Measure 3 3/4" high x 3 3/8" diameter. I am also including a set of 2 very similar vintage MCM stoneware mugs. No makers mark on mugs, simply stamped “Made in Korea”. No chips or cracks. One mug has a tiny lighter coloured spot in the glaze near the rim, which would have happened during manufacturing. Measure 3 1/2" high x 3 1/4" diameter.
