I received this as a gift, so I don't know the details, but it appears to be a rare American vintage mug. The indescribable expression and writing are unique, and I had it displayed on a shelf, but I'm selling it to declutter. I haven't used it as a mug. - Design: Unique character ceramic mug - Material: Ceramic - Shape: Mug with a handle - Features: Three-dimensional face design Height: 11.5 cm, Width: 12.5 cm (including handle), Diameter: 8.2 cm Thank you for looking.
