PURPOSE:To obtain a picture which gives a three-dimensional feeling, by providing V-grooves having prescribed conditions and printing the picture in such a way that the images reflected in the right eye are not reflected in the left eye and those reflected in the left eye are not reflected in the right eye. CONSTITUTION:A surface structure having grooves of an angle theta deg. of b'bc' (theta deg.30 deg.) is installed to the surface of printing paper made of paper, metal, plastic material, etc. The mountain-shape structure is formed in such a way that the surface b'-b can be viewed by the left eye and cannot be viewed by the right eye and the other surface b-c' can be viewed by the right eye and cannot be viewed by the left eye when the surface of the printing paper is viewed by both eyes from a point which is about 30cm apart from the surface. A picture is printed on the surface of such printing paper by a special printing method.
