Vintage Hand Painted Pier 1 Imports Monkey Chimpanzee Stoneware Coffee Mug. Dishwasher and Microwave Safe. I guess a normal manufacturer defect because it came like this new with a small dent in the glaze at the brim and small round hole under arm, see last 2 photos. It's big and hold a lot of liquid, somewhere between 16 and 20 ounces. Approximate measurements: 5" tall, 4.25" diameter at brim 3.25 diameter at base Made in China
