A.P.J Andy Warhol Ring Notebook - Shoes This is an original stationery series by Andy Warhol, one of the greatest artists of the 20th century. This is a popular B6-size ring notebook. The notebook inside has 5mm grid lines, making it easy to use. It comes with a rubber band, so you can store it neatly in your bag. I received this as a gift, but I'm not going to use it, so I'm giving it away.
