Patent US 5,487,566

A combined advertising brochure and separable reusable envelope device formed from a rectangular sheet being portioned and folded through the application of grouped parallel scorelines (242) and/or perforation lines (221). Additional format ad space is provided amidst given vertex fold points through the mounting of preassembled leaflet configurations (261A), either of which are attached to the brochure via a release adhesive (301). The further formation of a separable reusable envelope, and accompanying ad contents (40), becomes incorporated on at least one end of the brochure embodiment. Furthermore, the free standing aftermarket envelope portion becomes closed through the engagement of the tuck-in tongue enablements (381A and 381B). Likewise, the aftermarket envelope is enhanced with a categorical title strip (281) located about the exposed inside back panel of the envelope. Moreover, the aftermarket envelope portionment is further enhanced via the (landscape) pictorial ad field (421) which spans the aftermarket envelope's front side.
