Abstract: A blank for making an envelope from paper sheet stock and an envelope made from paper entirely or partially coated with a microencapsulated material that produces a visible record copy marking upon application of a force thereto and creation of an original marking thereby. The blank and the envelope have a first panel having a sealing flap and a pair of end flaps. A second panel is connected to the first panel, a third panel connected to the second panel, and a fourth panel connected to said third panel. At least the third and fourth panels are made from a front coated carbonless paper. Optionally, the fourth panel includes a back coated carbonless paper. Assembly of the blank to create the envelope and use of an instrument on the assembled envelope permits a user to create an original marking on a panel and simultaneously create a visible copy of the marking on another panel of the envelope by applying a force with the instrument.
