The Mystery of Three Letters That Disappeared A Super Bowl mural in Jersey City was reworked to allay possible trademark infringement concerns on the part of the N.F.L. Hiroko Masuike/The New York Times JERSEY CITY - Sometimes artists rework their paintings, touching up a face here or lightening the background there. Sometimes, as in the case of the mural with the disappearing logos, it is done for them, and not for artistic reasons. "Jersey City welcomes Super Bowl XLVIII," declares the mural in tall, silvery letters and Roman numerals between outsize images of the Vince Lombardi Trophy, which is given to the winning team. The mural also has two images that originally looked like the National Football League's logo, a blue shield with a football and stars at the top and red letters in the center - an N, an F and an L. But the center of the shield has been painted over, obscuring the letters. Abdul Gonsalves, perhaps better known as the graffiti artist Paws21, said he had painted the letters when he painted the mural. So why did they disappear? "You would have to get in contact with City Hall," Mr. Gonsalves said. Jennifer Morrill, a spokeswoman for the city government, said the letters were painted over because of concerns about using the N.F.L. logo without the league's permission. "The N.F.L. is rightfully very protective of the N.F.L. brand and logo," she said. We have worked closely with the League on multiple fronts as both Super Bowl teams are staying in Jersey City. She said that when someone noticed the logo on the mural, "we had it removed." Mr. Gonsalves, who lives here and has a studio in Paterson, N.J., said he was excited that New York and New Jersey were the hosts of the Super Bowl this year. He also said he was pleased that the teams would be billeted here, in hotels a few blocks apart. But he is not one to talk about which teams he is rooting for in the conference championship games on Sunday. "I don't really follow football much," he said. I'm not really a sports fan. A Mayor Objects Mayor James L. Cassella of East Rutherford, N.J., the town in which MetLife Stadium is situated and the Super Bowl will be played, has long complained that New Jersey would be forgotten in this, the first Super Bowl with two states as hosts. Where are the N.F.L. offices? The Fox network offices?" he asked in November. They're in New York City. Therefore, where do you think the emphasis is going to be? This week Mr. Cassella added a commercial for Verizon FiOS to his litany of complaints. In the commercial, a sequel to one about an 8-year-old girl who used the Internet to learn so much about football that she became a television commentator, a network executive tells the girl and the sportscaster Terry Bradshaw: "So, about February. I can only send one of you to cover the game in New York. (The girl and the network executive are actors. Mr. Bradshaw and Erin Andrews, another sportscaster seen in the commercial, play themselves.) The girl bones up with computers and television monitors in her room, and is chosen over Mr. Bradshaw. "You're going to New York," the network executive says. A camel named Princess, who lived on a New Jersey estate, was said to have a knack of predicting the winner of football games. John Bergmann/Popcorn Park That was too much for Mr. Cassella. "They're going to New Jersey," he all but shouted at a news conference this week. The Verizon FiOS executive who oversaw the commercial, Deirdre Robinson, said she had nothing against New Jersey - she not only works there, she also lives there. Her office in Basking Ridge is about 40 miles from East Rutherford. But much of the brainstorming on the commercials was done with the advertising agency on the project, McCann Erickson New York. "Usually," she said, "we'd go to their place, because their place is the cooler place." And McCann Erickson is in Midtown Manhattan. She said the script was worded the way it was because there was so much to get across in a short time. In a 60-second commercial, she said, "it was very difficult to communicate East Rutherford, N.J." "We just assumed most people referred to this area as the New York metro area," Ms. Robinson added, "and it includes New Jersey." Mr. Cassella had heard that before. "I'm used to it," he said. Bettors Lose a Guide Predictions about who will win the conference championships or the Super Bowl itself? One prognosticator with a pretty good record will not be heard from this year. Princess, a Bactrian camel - "Two humps," said John Bergmann, the manager of the New Jersey zoo where she lived - was euthanized on Wednesday. She correctly picked the Baltimore Ravens to win the Super Bowl last year and the Pittsburgh Steelers to win in 2008, when she predicted the right result in 17 of 22 games, or 77 percent. This season, she had slipped to 57 percent, calling only 11 of 19 games correctly. Princess had lived on the farm of the heiress Doris Duke in a central New Jersey estate before she was sent to Popcorn Park, a zoo run by the Associated Humane Societies of New Jersey. She and Mr. Bergmann soon worked out a way for her to communicate her thoughts about which team would win, week after week. He would write the names of competing teams on each of his hands, cover the names with a graham cracker and reach out. He recorded her prediction based on which hand she ate from. "People would call on Sunday morning to ask who she'd picked," Mr. Bergmann said. I guess before they'd put their bets down. One guy wanted her to go to Atlantic City with him. I said, "If I could go with her." "
