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 beautiful, textured base. Size: Diameter: 3.5cm Height: 3cm This item is from a collection of antiques and folk art that my grandmother, who loves old tools, Sakata's antique shop, the Mejiro Collection, and primitive art, has been collecting for over 50 years. It is a very valuable piece, and my grandmother displayed it in a cabinet. However, due to a move and a desire to downsize, she is reluctantly parting with her collection and would like to pass it on to someone who appreciates it.
