Some more details from the Apollinaire wikipedia page:
> On 7 September 1911, police arrested and jailed Apollinaire on suspicion of aiding and abetting the theft of the Mona Lisa and a number of Egyptian statuettes from the Louvre, but released him a week later. The theft of the statues had been committed in 1907 by a former secretary of Apollinaire, Honoré Joseph Géry Pieret, who had recently returned one of the stolen statues to the French newspaper the Paris-Journal. Apollinaire implicated his friend Picasso, who had bought Iberian statues from Pieret, and who was also brought in for questioning in the theft of the Mona Lisa, but he was also exonerated. In fact, 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.
Maybe I'm misreading either TFA or your comment, but both Picasso and Apollinaire were alive in 1911?
