Aerogramme contains a blank page available to the sender for completion at his request. The upper part of it contains the wording AEROGRAMME, and there is space to note the addresses of the recipient and sender.
The folded Aerogramme has a seal sticker (like the envelopes) that is used to close the aerogramme so that the content cannot be read. The recipient shall wait for the aerogramme ate the underlined location, and will be allowed to unfold the aerogramme.
