This is a collection of photographs newly produced based on a work from 2005 in which tried to think about reproduction and its medium. A postcard-sized eraser (148 x 100 x 11 mm) is split in two by inserting the blade of a cutter from the side, and photographed with light shining on each. The marks made by the blade, which requires a little force and is difficult to control, are engraved on the eraser as an improvised image, and at the same time, another image is created as a mirror image. The two sets of cut images are superimposed once again by the movement of the eyeballs or by folding the image.
