A verifiable holographic article comprises a substrate comprising (a) at least one hologram; and (b) at least one covert image that is convertible to an overt image using a decoding sampling device, e.g., a photocopier, that produces an aliasing or moire effect. The article cost-effectively provides both 'first line' and 'second line' security features and can be easily, quickly, and safely verified or authenticated.
