Abstract

The invention relates to a two-way communication sheet in the form of double post card (1-4), double letter sheet (5-9), or the like for use in communicating under cover written information and the like which should be protected from disclosure. The two-way communication sheet is so arranged that a sheet portion on which information is written is bonded to other sheet portion or portions when the communication sheet is initially forwarded as well as when it is sent in reply, so that the information is prevented from being exposed outside. The communication sheet is quite novel in that it enables information to be communicated in secret condition.
