The stamp depicts the development of the means of postal and other communications from ancient times until the present. At the very bottom of the stamp can be seen an inscription on clay, called "Calev". This inscription, which, it would seem, is from the 17th century B.C. E., is in one of the oldest of alphabets, called Proto-Cananite. Above this inscription is a piece of Egyptian hieroglyphic writing, engraved on a monument. Above the Egyptian writing is a short passage from the inscription of Mishah, King of Moav, from the 9th Century B.C.E. The language of the inscription is Moabite which is similar to Hebrew, and the script is Hebrew script, so this well represents the beginning of the written tradition in Hebrew. The rider in the sketch above the inscription of Mishah, is a Jewish postman from Prague, blowing his post-horn. The sketch was taken from a copper engraving from the year 1741. Then above the postman, one after another, can be seen the means of communication used in our own day: the envelope; radio waves; a computer terminal; binary coding (),1) and a satellite aerial.
