I think this is just a copy or print of Agnolo Bronzino "Portrait of A Young Man with a Book"
On the back of the Painting there is a tag that says:
The Frame Shoppe
Custom Framing
Fine Prints
and Artists Materials
436 sixth avenue
corner of 10th street
New York,NY
ALGONQUIN 4-1815
There is a small bubble or something on the left side of his nose and to the right of his shoulder. Otherwise it is in rather good condition. Maybe a few scratchs on it.
The Dimensions of the painting without the frame are:
Height: 37" 3/4
Width: 29''
This portrait—among Bronzino's most arresting—was painted in the 1530s. The sitter is not known, but he must have belonged to Bronzino's close circle of literary friends in Florence, a number of whom sat for the artist. Bronzino himself composed verses in the style of the great Florentine poet Petrarch (1304–74), and the fanciful and witty details in this picture—the carved grotesque heads on the table and chair and the masklike face suggested in the folds of the youth's breeches—would have been appreciated by writers as comments on masks and identity. The book is doubtless a collection of poems. For a technical study of the changes Bronzino made to the painting as he worked see metmuseum.org/collections.
