In the 1970s, CHOI Byungso repeatedly erased newspapers with pencils and ballpoint pens to show his existence as an injustice of meaning. Instead of canvas and paint, the writer chooses newspaper and ballpoint pen, which are easily seen in daily life, as the main ingredients for his work. After countless repetitions with a ballpoint pen on a newspaper full of type, even the traces of the ballpoint pen are erased with a pencil, leaving a black monochromatic screen. Newspapers are similar, thinned or torn, and eventually turned into shiny black skins. In this way, the writer is absorbed in integrating the newspaper with the ballpoint pen. They are absorbed and brought into contact with each other and broken, and generate heat and burn by friction. Through this process, Choi Byung-seo experiences living things and trains his mind. Newspapers are then reborn as one noble and pure substance.
