The drawings can be dated from their style and the contemporary costumes to the 1450s up to Finiguerra's death in 1464. They agree strictly with the accounts of Finiguerra's drawings left us by Vasari and Baldinucci, and disagree in no respect with the character of the inlaid figures of the sacristy. That he was probably also an engraver in niello appears from the fact that figures from the Uflizi series of drawings are repeated among the rare anonymous Florentine niello prints of the time (the chief collection of which, formerly belonging to the marquis of Salamanca, is now in Edmond de Rothschild Collection at the Louvre).
