Der Goldschmiede Merkzeichen: Ausland und Byzanz
Der Goldschmiede Merkzeichen: Ausland und Byzanz is a 1928 German reference work by Marc Rosenberg, held by Heidelberg University Library, cataloguing foreign and Byzantine goldsmiths' marks for specialists in metalwork. The pictures are photographs of struck marks on round metal discs, shown as small clusters of punched stamps with crosses, crowns, letters and animal forms; a designer could draw on their dense, irregular stamped geometry for textures, badges or distressed monogram layouts.
