Abstract
A form is provided having a fold line dividing the form into a first panel and a second panel. Hidden information is provided within the first panel. The second panel is suitably impregnated with a transparentizing composition such that a transparentized window portion is defined integral with the second panel. A decoder is constructed comprising the transparentized window portion. The positioning of the hidden information within the first panel, and the decoder in the second panel is such that when the form is folded along the fold line, the hidden information becomes apparent to a user by viewing the first panel in conjunction with the decoder.
