A personalise stamp is a postage stamp where a picture or photograph can be added to the stamp by a member of the public, some non-governmental entity, or a governmental entity that is not in an official stamp-issuing capacity; it is obviously to be distinguished from personalised rubber stamps as well as "Postal Pal," a label with picture on which a regular postage-stamp can be placed. (In Austria the denomination of personalised stamps can now be changed as well.) In addition to mere personal expression the design of personalized stamps have served a number of other purposes such as the attempt to find missing persons. Some stamp-issuing entities have in turn used their personalised stamp systems to issue "personalised" stamps personalised by the stamp issuing entity.
