For a limited time, Teefury is offering up a Marvel-themed Super Bowl XLIX charity t-shirt called Chris vs Chris for only $11.

The t-shirt, which pits Captain America (The Avengers) against Star-Lord (Guardians Of The Galaxy was inspired by TwitterBowl, the Super Bowl wager that began on Twitter earlier this month between two Marvel superhero actors — Boston, MA, native and New England Patriots fan Chris Evans aka Captain America, and Lake Stevens, WA, resident and Seattle Seahawks fan Chris Pratt aka Star-Lord. But what started out as a rivalry quickly turned into a wager for charity: If the Patriots win, Pratt as Star-Lord will visit Christopher’s Haven in Boston, MA; if the Seahawks win, Evans as Captain America will visit Seattle Children’s Hospital in Seattle, WA.

Head over to Teefury to order the Chris vs Chris t-shirt, which will be available through February 10, 2015.

Super Bowl XLIX will take place at the University of Phoenix Stadium in Glendale, AZ, on Sunday, February 1, 2015 at 6PM and will be broadcast live on NBC. We’ll see which superhero’s favorite team wins. (I have a feeling that no matter which team wins, both actors will make the charity appearances.)
