The self-adhesive label (10) produced in relief in order visually and/or in a tactile manner to simulate decorative etching of the material of a container or a decorative seal or stamp applied to the container, includes: a layer of adhesive (105); a sheet of flexible plastic (110), one face of which is entirely covered by the layer of adhesive; and an extra thickness (120) formed on the opposite face of the sheet of flexible plastic to the layer of adhesive. The extra thickness includes a flexible plastic and covers the edge (115) of the sheet to form a decorative design simulating an engraved relief. The peripheries of the extra thickness and of the sheet of plastic are cut jointly, the cut edge of the extra thickness thus coming as a continuation of the cut edge of the sheet up to the lower surface of the sheet of flexible plastic.
