That photo of the Tomb of the Unknowns guard in the rain? It’s from September

A blood-stirring photograph of sentinels at the Tomb of the Unknowns in Arlington National Cemetery is bucking up hurricane-soaked people in the Mid-Atlantic and Northeast Monday. Well, sorry, but it’s actually from last month, taken by a photographer named Karin Markert.

I took some pics at the Tomb of the Unknown Soldier at Arlington National Cemetery today, in the rain… smugmug.com/gallery/254471… — Karin Markert (@KMarkert88) September 18, 2012

Still, it’s a pretty sweet shot.

The photo that circulated on Twitter and Facebook did not have the photographer’s credit, which appears above.

It appears the photo started to spread after it was posted on Facebook by the First Army Division East. It was shared more than 53,000 times and liked more than 43,000 times.

Markert explains in a comment below: “I was using it as my Facebook cover photo, which apparently is “public”, and what do you know? … Nobody “stole” it, IMHO. My guess is people are just sharing how proud they are of these soldiers and others.” On Facebook, she elaborates:

Apparently the picture has gone ‘viral,’ which is kind of shocking me today. I’ve seen it a bunch of places, with credit given to a whole lot of other sources. That just doesn’t matter to me. What’s most important, and please remember this, is that no matter how the photo ended up on everyone’s computer, I am just so very proud of these soldiers and the mission that they fulfill every day.

NPR picked up the photo, along with The Washington Post, The Daily Beast, Talking Points Memo, Slate and others.

This photo was taken today at the Tomb of the Unknown Soldier, posted by the 3rd U.S. Infantry Regiment and sent to Poynter with permission to publish:
