Two early original 1766 copper engravings from a book titled “Heads of Illustrious Persons of Great Britain” published by John Knapford, by Houbraken and Vertue and Birch. See pictures for details. One page is about Robert Rich and the other about Henry, Prince of Wales. Both are protected by a durable plastic sleeve. Very cool piece of history! Great for the collector of books and antiques.
