In tradition, artists in metal "signed" their work with a touchmark. A touchmark is an acronym or symbol which represents an individual or shop. It is usually a stamp or punch with a positive image (reversed or symmetrical) which is indented as a negative image - right reading. (Source: http://artist-blacksmith.blogspot.com/)
