Claim: A drawing of Francesco Gonzaga signed off in 1499 to the photographer Andrea Mantegna and Giovanni Bellini.
Evidence: Andrea Mantegna (UK: /mænˈtɛnjə/, US: /mɑːnˈteɪnjə/, Italian: [anˈdrɛːa manˈteɲɲa; c. 1431 – September 13, 1506) was an Italian painter, a student of Roman archeology, and son-in-law of Jacopo Bellini. Another work of Mantegna's later years was what is known as the Madonna della Vittoria, now in the Louvre. It was painted in tempera about 1495, in commemoration of the Battle of Fornovo, whose questionable outcome Francesco Gonzaga was eager to show as an Italian League victory; the church which originally housed the picture was built from Mantegna's own design. The Madonna is here depicted with various saints, the archangel Michael and St. Maurice holding her mantle, which is extended over the kneeling Francesco Gonzaga, amid a profusion of rich festooning and other accessories.
