The Isleworth Mona Lisa is an early sixteenth-century oil on canvas painting depicting the same subject as Leonardo da Vinci's "Mona Lisa", though with the subject (Lisa del Giocondo) depicted as being a younger age. The painting is thought to have been brought from Italy to England in the 1780s, and came into public view in 1913 when the English connoisseur Hugh Blaker acquired it from a manor house in Somerset, where it was thought to have been hanging for over a century. Since the 1910s, a number of experts in various fields, as well as the collectors who have acquired ownership of the painting, have asserted that the major elements of the painting are the work of Leonardo himself, as an earlier version of the "Mona Lisa".
