Verkündigung der Bulle Pastoris, 1479

This 1479 papal bull from Pope Sixtus IV features two nearly-identical collation notes by papal notaries, identified by their initials in the seals to the left of their notes as Gregorius May and Mathias Horn. The huge and intricate initial I is handwritten and the bull is printed on parchment, both features which hearken back to the established and respected tradition of manuscript bookmaking.
