"Diploma" or decree granting to Paulus Manutius the use of an individual printer's mark. Issued at Prague, 28 April, 1571.

Folded; in modern blue case.
Printed on vellum, with the mark inserted in the center.
See Ren. p. 412 and 214.
This was the 6th printer's mark of the Aldine presses, and was used by Paulus Manutius from 1571-1581 though not entirely superseding his use of an earlier mark, a simple anchor.
