The abstract describes 'a fine perforation group is formed on the hologram where a visible image is formed by diffraction grating or the like, and the perforation group is optionally disposed to form the plurality of invisible images
. One of the plurality of invisible images
can be visually observed when light is transmitted through it, and further when light is transmitted and a discrimination implement is superposed on the base material for visual observation, the other invisible images
can be visually observed.
