Guillaume Apollinaire returned one of the stolen statues to the French newspaper the "Paris-Journal". Apollinaire implicated his friend Picasso, who was also brought in for questioning in the theft of the "Mona Lisa", but he was also exonerated. The theft of the "Mona Lisa" was perpetrated by Vincenzo Peruggia, an Italian house painter who acted alone and was only caught two years later when he tried to sell the painting in Florence. Apollinaire wrote the preface for the first Cubist exposition outside of Paris; "VIII Salon des Indépendants", Brussels, 1911. In an open-handed preface to the catalogue of the Brussels Indépendants show,
Vincenzo Peruggia with banner headlines rejoicing its return and then returned to the Louvre in 1913. While the painting was famous before the theft, the notoriety it received from the newspaper headlines and the large scale police investigation helped the artwork become one of the best known in the world. Peruggia was released from jail after a short time and served in the Italian army during World War I. He later married, had one daughter, Celestina, returned to France, and continued to work as a painter decorator using his birth name Pietro Peruggia. He died on October 8, 1925 (his 44th birthday)
