Blub is an Italian street artist whose real name is as much a mystery as Banksy's. He has added snorkel masks to a string of classics, including the Girl with a Pearl Earring, da Vinci's Mona Lisa and Piero della Francesca's Duke and Duchess of Urbino (the 15th century original of which graces the city's hallowed Uffizi Gallery).
