An object (1) comprising a region (R) of its surface suitable for showing a plurality of images each observable from a different direction such that upon observing one of the images the other images stop being visible. The region comprises a plurality of cavities (1.1) in low relief regularly distributed on the surface of the region (R), each of the cavities (1.1) shows a plurality of side facets 10 (1.1.1, 1.1. 2, 1.1. 3), at least one facet per image, where each facet (1.1.1, 1.1.2, 1.1.3) is associated with either a first light level or a light level different from the first. The configuration allows for mass production by means of stamping or minting techniques and complicates the reproduction by unauthorized manufacturers. A method for producing a stamp for the production and a method for production is also included. |
