Spain released a stamp on Mailboxes.In Spain there were no mailboxes to deposit the post until 1762 and it was delivered by hand to the mail clerk. That year an official provision established opening a : “hole or fence in all paths in which to throw the letters without being able to receive them by hand.” This avoided suspicion arising at the possible loss of shipments whilst providing better service by not having to wait for the “driver” to hand over the mail. Since then and over the years post boxes have varied in shapes, decorations and materials used in their manufacture. The stamp depicts a mouth-mailbox of white marble with a carved lion’s head topped by a crenellated tower. It was installed in the Casa de Postas in the Puerta del Sol, former headquarters of the main post office in Madrid until 1916.It is part of the collection of mailboxes of the Post and Telegraph Museum which is responsible for the maintenance and custody of exhibits and documents relating to the history of mail, telegraph and philately.
