B. Platinæ Cremonensis opus, De vitis ac gestis summorum pontificum ad Sixtum IIII. Pont. Max. deductum
This is a 1645 Latin history of the popes by Bartolomeo Platina, printed in the Netherlands with an unidentified publisher and later owned by John Adams. The three pictures are printer's ornaments: a shield-like cartouche with winged figures and a central mask, a hanging strapwork ornament with a crab-like motif, and a large initial N inside a leafy scrolled frame, all cut in crisp black on cream paper.
