“For all those who are in the situation of Hero and Leander, and similarly to them can only exchange secret signs about the feelings of their hearts, here we publish the secrets of the language of stamps. If the stamp stands upright in the upper right corner of the card or envelope, it means: I wish your friendship. Top right, across: Do you love me? Top right, upside down: Don’t write me any more. Top right, thwart: Write me immediately. Top right, upright [once more again???]: Your love makes me happy. …”
Once upon a time there was a language of stamps. Sadly, with the demise of stamps (and secrets?) the language has disappeared.
