Have you heard of the Language of Stamps?
I was just reading an article from The Postal Museum on How to Write a Postcard and it mentions the Language of Stamps. This isn’t something I had heard of before, but according to the article it’s a way of sending a hidden message to the recipient of a postcard via the stamp. You do this by angling the stamp in different directions which gives the stamp different meanings.
For example, rotating the stamp 90 degrees anti-clockwise sends the message ‘Answer at once’. You can click here to view the other variations and their meanings mentioned in the article.
Is this something you were aware of and have you ever used this secret language to send a hidden message on your postcards?
