Much the largest group of drawings is in the Uffizi, some of which are inscribed "Maso Finiguerra" in a seventeenth-century writing, probably by Filippo Baldinucci, curator of the Medici collections. These depict many figures of the studio and the street, to all appearance members of the artists own family and workshop, drawn direct from life, and used "as a repository of figural ideas that could be used by Finiguerra to speed up the compositional process". The Uffizi group includes 14 studies of birds and animals, some apparently copied from other drawings, such as a rather stylized cockerel.
