The history of the Hanseatic League lacks a larger collection of documents from a single society, only in the case of the Veckinghausen did it become a more vivid picture under Wilhelm Stieda's hands. The thirst for letters and the hunger for business records also dominated the history of Upper German trade. Only then do we truly see figures like Jakob Fugger, Hans Kleeberger, and the printers Anton Koberger and Bonifazius Amerbach come to life. Alongside the letters and documents, portraits also emerge. A completely unexpected discovery has led to a transformation, revealing not the papers of an insignificant merchant, but remnants of records and correspondence from the largest German trading company that existed before the era of the Fuggers, into which it also extends with the last third of its one hundred and fifty-year duration. In one location, these records of the great Ravensb. were found.
