Abstract
A mailer type business form is provided which includes an outgoing envelope formed by a first sheet folded along a fold line to provide first and second panels each having three marginal edge portions, and a return envelope formed by a second sheet overlying the second panel and adhesively secured to the second panel inwardly adjacent the three marginal edge portions such that the second panel forms a rear panel of both the outgoing envelope and the return envelope. A removable tear strip is incorporated in the second panel and is defined by a slit formed in the second panel parallel to and adjacent one of the marginal edge portions, and a pair of parallel lines of perforations extending perpendicularly from opposite ends of the slit toward the fold line.
