Confitendi ratio Doctoris Martini Lutheri Augustiniani VVittenbergen[si]
A 1520 Latin religious tract by Martin Luther, printed in Augsburg by Silvan Otmar for a learned clerical readership, with the plain bookplate-style frame of a Boston Public Library copy. Its only picture is a small engraved bookplate showing a laurel-wreathed circular seal with figures and a label reading Charlotte Harris Fund, so a designer might take its wreath and seal framing as a compact emblem layout.
