Abstract: A stamp having a fixed text as well as an interchangeable text comprises a base member having a recess in the under side thereof to receive a printing member for the fixed text. The interchangeable text, for instance date indications, is obtained by means of separate stamp units, each having in its upper portion a handle portion and an indication of the text of the stamp in question and in its lower end the printing member for said text and is insertable in a through opening of the base member. The stamp unit and the base member further have interengaging means to lock or latch each stamp unit in a position in which the printing surface of said stamp unit is in level with the printing surface of the fixed stamp.
