The story

A commercial telegraph code stood standardised code groups in for longer phrases, so that international business messages cost less to send. This 1929 supplement to the Rudolf Mosse code, compiled by Julius Kähler, gives tables for users of German, English, French, Spanish and Portuguese, with currency figures and alphabetic aids for building code groups.

An illustrated endpaper shows the firm’s Berlin headquarters, remodelled by Erich Mendelsohn. A separate printed errata slip corrects several encoded entries: in a code book, a wrong group is a wrong message.
