In addition to the post offices of Turkey, Austria, France and Russia operating in the city of Jaffa at the end of the 19th century, letter writers in the city had another way to send their letters. The ships that docked in the port of Jaffa used to hang a special box overboard, in which those interested could put their letters. The ships that sailed from Jaffa to Port Said in Egypt delivered the letters to the local post office, where the stamps were stamped with a special stamp. A postcard kept in the Alexander collection is an example of this procedure.
