SOLUTION: The double postal card paper is formed of a forward delivery postal card form and a reply postal card form connected together through a folding line, with the concealing label unpeelably attached to a specified position of the forward delivery postal card form. The concealing label has each row of perforations for cutting formed along each of both right/left end edges of a label base material, and a paste with the function of reattachment of the label base material located inside of each row of the perforations. Further, an adhesive paste, which is reattachable, is applied to the back of the label base material located outside of each row of the perforations. Besides, in the forward delivery postal card form, the region is provided where the concealing label is attached in a releasable state and the adhesive paste, which is applied to the back of the label base material, is reattachable and unpeelable after reattachment, and brought into contact with the region. This region is treated for the concealing label to be releasable after attaching it with the help of the adhesive paste. COPYRIGHT: (C)2009,JPO&INPIT
