Anderson pottery is the name given to Dr. Anderson, a Swedish man who first discovered this type of pottery.
There are several shapes of Anderson pottery, but this product is an extremely rare leather bag-shaped pottery. This style was introduced to Japan from Silla, and a small number of Sue ware skin bag-shaped pottery still exist today.
A jewel-like pattern is drawn on both sides of the torso. It is in good condition and is in perfect shape.
I think it's museum quality. Would you like to have a collection?
