Abstract
A multi-layer hologram label includes a base layer having a surface on which a number of layers of adhesive materials are coated in a stacked manner. Each layer has a surface on which a pattern associated with a holographic image is formed whereby by sequentially removing the layers, the patterns of the next layers are sequentially exposed for displaying the associated holographic image. The layers of adhesive materials can be replaced by hologram films carrying hologram patterns thereon. By sequentially removing the hologram films, the hologram patterns of the next films are sequentially exposed to display holographic images associated therewith.
