This is a small white porcelain cup from the Joseon dynasty, purchased by my grandmother in Korea during her travels in the 1990s. It has a thick, glossy glaze and a beautifully textured base. Size: Diameter: 3.5cm Height: 3cm This item is from a collection of antiques, folk crafts, and primitive art that my grandmother, a great admirer of Ko-dōgu Sakata, Mejiro Collection, and other world antique dealers, has amassed over 50 years. It is a very valuable piece that my grandmother displayed in her cabinet, but she is reluctantly selling it to someone who appreciates it, as she is downsizing her life due to a move and needs to organize her collection.
