The history of the Hanseatic League lacks a larger collection of documents from a single society; only in the case of the Veckinghausen does it present a more vivid picture under the hands of Wilhelm Stieda. The thirst for letters and the hunger for business records also dominated the history of Upper German trade. Only then do we see figures like Jakob Fugger, Hans Kleeberger, and the printers Anton Koberger and Bonifazius Amerbach come to life. In addition to letters and documents, portraits also play a role. A completely surprising discovery has now brought about a change, revealing not the papers of an insignificant merchant, but remnants of documents and correspondence from the largest German trading company that existed before the era of the Fuggers, which it indeed overlaps with during the last third of its one hundred and fifty-year duration. In one location, these documents of the great Ravensb. were found.
