Okay, this is super meta — but also super cool for photojournalism geeks like myself.

In the seconds after the tragic Boston Marathon bombing this morning, Globe photographer John Tlumacki snapped this harrowing and widely-circulated image of 78-year-old runner Bill Iffrig on the ground, three policeman springing into action around him.

But check out the AP image above, taken from the bridge above the finish line just seconds before the Globe photo.  If you look carefully, you can actually see Tlumaki in a yellow vest, camera poised, about to take the now-famous photo.
