The above print is “Tramps! A Miscellany of Printers Portraits” — a limited edition two color letterpress print by Dan Wood and Katherine Cummings. They used images selected from the hundreds of recently scanned printers portraits at the Daniel Berkeley Updike History of Printing Collection in the Providence Public Library and focuses on early printers of the 15th and 16th centuries, with Benjamin Franklin and a few other later eccentrics thrown in for good measure.
Available for sale here. First seen on the printeresting blog.
Side note: The Providence Public Library Special Collection has a nice blog called Notes for Bibliophiles.
