As we learned in August, photographer Katherine Kostreva created the City of the Brave calendar after her life was saved by a firefighter; since then, the 26-year-old has "made it her artistic mission to honor the firemen's selfless bravado and their muscular bodies." Now we've got a sneak peek at the 12 Hunks of 2011, and we're told that on January 13th (at Sidebar on East 15th Street) you'll be given a chance to bid on these Bravest!
