A few nice Super Bowl XLIX images I found:

University of Phoenix Stadium, opened August 1, 2006, is a multipurpose football stadium located in Glendale, Arizona. It is the home of the Arizona Cardinals of the National Football League (NFL) and the annual Fiesta Bowl. The stadium is located next door to the Jobing.com Arena and it features the first fully retractable natural grass playing surface built in the United States on top of an AirField Systems drainage system. An opening on one side of the stadium allows the playing field to move to the exterior of the building, allowing the entire natural turf playing surface to be exposed to daylight.
The stadium has hosted Super Bowl XLII, and the 2011 BCS National Championship Game, a game that it hosts every four years, which set the venue’s entertainment attendance record of 78,603 on January 11, 2011. It will again host Super Bowl XLIX in 2015.
The University of Phoenix acquired the naming rights in September 2006, shortly after the stadium had opened under the name Cardinals Stadium. The "University of Phoenix" name is applied as a corporate sponsor, and not as the home stadium of the University (which has no intercollegiate athletics program).
