I have a manuscript from the late 15th to early 16th century, likely from Erfurt, with a translation mentioning names like Franz de Sachsa, Mathias, Heinrich Gispersleben, and potentially Eobanus Hessus. The manuscript is on parchment used to cover a 1540 Variata edition of the Augsburg Confession. I am based in Atlanta, Georgia, and purchased the book from a Germany bookstore in Gotha. How can I research and potentially sell this manuscript?
