Abstract
Methods of creating tamper resistant informational articles and related products are disclosed. In one embodiment, a lens has a preformed transparent hologram, metallized portions are provided and may be altered through selective application of heat to predetermined parts thereof to create information which may be fixed or variable. Printing may be provided on the hologram before metallizing. A base portion underlies the metallized layer. In yet another embodiment of the invention, an opaque base portion has a hologram formed in the upper surface thereof with portions of the hologram being made readily visible by partial metallization covering only portions of the hologram with or without information provided as by printing overlying or underlying portions of the metallized sector or both. A transparent overlying lens is secured in overlying relationship. Metallizing may be such as to permit viewing underlying hologram portions or information or not. A corresponding method is provided.
