It was a huge box of antique documents. Interestingly, a few carried the Nazi mark of 1940s Germany. I was then able to find out what was added to the documents requisitioned to send to Berlin for special treatment.
I don't know what you can say the document or why it was requisitioned, this is in very old Spanish and calligraphy is not my forte precisely. In any case it is a beautiful historical document from 1557 (dated in the document), authentic and marked by Nazi Germany as of interest to take away for some reason. They are 4 sheets in total.
