Abstract
Abstract The documents illustrated are lottery tickets, each having a number concealed by being printed on a base sheet having a twoply cover means including an intermediate sheet and a cover sheet. The intermediate sheet is opaque and extends over the area on the base sheet where the number is printed. The upper side of the intermediate opaque sheet is coated with a wax. The cover sheet is larger than the intermediate sheet and the under side of the cover sheet is coated with an adhesive material which forms a strong bond with the paper of the cover sheet and of the base sheet, and a relatively weak, releasable bond with the wax on the opaque sheet. One edge of the opaque sheet is engageable with the fingernail so that the opaque sheet may be lifted, thereby tearing the cover sheet along the edges of the opaque sheet and revealing the concealed number. The cover sheet is not weakened along lines registering with the edges of the opaque intermediate sheet. Nevertheless, the cover sheet is provided with short diagonal cuts diverging from those lines into the surrounding portions of the cover sheet. These cuts are effective to lead a tear along such a line intermittently into those surrounding portions so that tearing produces an irregular edge which it is practically impossible to restore to its original appearance. The margins of the cover sheet, where it adheres to the base sheet, are cut to define a multiplicity of small localities enclosed by cuts. If an attempt is made to peel the adhesive coated cover sheet away from the base, then some of these small localities stick to the base and become separated from the cover sheet. These small localities become slightly displaced from their original positions during that separation, making it practically impossible for the cover sheet to be removed and replaced without detection. Any attempt to restore the cover sheet to its original position will result in a misalignment between the cover sheet and some of the small enclosed localities which stuck to the base. The base sheet and the cover sheet have contrasting colors, so that any such misalignment appears in sharp contrast, revealing that an attempt has been made to read the concealed number. A method of making a multiplicity of such lottery tickets is disclosed.
