suggested is the date ca. 1465, for instance by Arthur M. Hind
Trionfi.com suggests 1475, assuming that Lazzarelli took strong influence on the development; as artist we suggest Sweynheim or an engraver near to him
Dürers work is suggested for 1495 and 1505, and it is not complete (21 or 22 pen paintings)
Lazzarelli, an author, not a painter, who according an insecure note found the paintings in a Venetian bookstore, worked ca. 1470 - 1474. He used 27 paintings in a manuscript as illumunations, which he gave to the duke of Urbino not before 1474. We suggest, that Lazzarelli composed the 50-pictures structure of the Mantegna-Tarocchi, likely 1474 or 1475, and realized the project in Rome with the help of Sweynheim.
Unluckily we don't have all pictures from Lazzarelli and some of our pictures are bad copies.
