A tourist poses for a picture Wednesday in front of a painting by Italian artist Mauro Pallotta depicting Pope Francis as Superman. The pope, holding a bag with the word "Values" written on it, is on a wall in the Borgo Pio district near St. Peter's Square in Rome. It wasn't enough that Pope Francis was named Time magazine's "Person of the Year" or that he fronted this week's Rolling Stone magazine. Now there's SuperPope graffiti sprouting up around the Vatican. Francis has charmed the masses with his simplicity and message of helping the poor, even as he has cracked down on Vatican waste and corruption. The Vatican approved of the image, tweeting a photo Tuesday.
