Portrait painting by Jean Clouet, LeadArt oil painting just do reproduction of them in museum quality on linen canvas:

Jean (or Janet) Clouet (1480–1541) was a miniaturist and painter who worked in France during the Renaissance. He was the father of Francis Clouet.
Jean Clouet was undoubtedly a very skillful portrait painter, although no work in existence has been proved to be his. He painted a portrait of the mathematician Oronce Finé in 1530, when Fine was thirty-six years old, but the portrait is now known only by a print. Janet is generally believed, however, to have been responsible for a very large number of the wonderful portrait drawings now preserved at Chantilly, and at the Bibliothèque Nationale, and to him is attributed the portrait of an unknown man at Hampton Court, that of the dauphin Francis, son of Francis I at Antwerp, and one other portrait, that of Francis I in the Louvre.
Seven miniature portraits in the Manuscript of the Gallic War in the Bibliothèque Nationale (13,429) are attributed to Janet with very strong probability, and to these may be added an eighth in the collection of J. Pierpont Morgan, and representing Charles I de Cossé, Maréchal de Brissac, identical in its characteristics with the seven already known. There are other miniatures in the collection of Mr Morgan, which may be attributed to Jean Clouet with some strong degree of probability, inasmuch as they closely resemble the portrait drawings at Chantilly and in Paris which are taken to be his work.
