The present invention relates to a document with counterfeit- and forgery-preventing means particularly for valued papers and the like, which comprise a sheet-like element (1) having, on at least one face, a graphic marking (10, 20) that is visible in reflected light. The particularity of the invention resides in the fact that it comprises at least one variation (30) in the thickness of said sheet-like element which provides a graphic representation that can be viewed against the light and is complementary with respect to the at least one graphic marking. <IMAGE> |
