In preparation for the one-year anniversary of the Boston Marathon bombing on April 15, Sports Illustrated Magazine brought together thousands of bombing survivors and Bostonians for the magazine's cover photo.

Three people were killed and more than 200 hundred were injured in the bombing last year, which nearly shut down the city.

Most of the attendees of the photo-shoot wore the blue and yellow colors of the Boston Marathon, while others held signs including a heart-shaped sign with "Boston" in the center, a blue Boston and flag and at least one American flag.

The crowd included first responders, the Boston police commissioner,the Boston Mayor marathon runners and a few people who had been severely injured in the bombing. The photograph will run on the next issue of Sports Illustrated.

The attendees included Carlos Arredondo, who became famous after he was photographed in his cowboy hat helping to wheel in a man who was severely injured in the blast.

Other survivors, some wearing prosthetics, brought along family members for the momentous cover issue. Other attendees cheered on the crowd, by literally doing a few acrobatic stunts.

People started arriving well before the 7am call time and the Associated Press estimated at least 2,000 people were in attendance. The photographer had to stand on an elevated platform to try and take in the whole scene.
