Abstract
An envelope insert for a magazine has a uniform double thickness of sheet material throughout so that a plurality of envelope inserts can be stacked evenly for automatic insertion into magazines. The envelope insert is comprised of substantially coextensive first and second sheets which have superposed edges. The first sheet has a perforation line which is spaced from the end of the first sheet, and the second sheet has a perforation line which is located between the end of the sheet and the perforation line of the first sheet to provide a flap portion on the first sheet between the perforation line of the first sheet and the perforation line of the second sheet. The flap portion is provided with adhesive so that it can be folded over the second sheet and secured thereto after the sheets are torn along the perforation lines.
