I recently went to NYC and got a walk on the High Line. I noticed ther that someone painted on a wall the famous Alfred Eisenstaedt picture of a sailor kissing a nurse in Times Square. I found it was rare to see a pictures reproduce outside the "photo perimeter" and displayed in a public place.

I tried to find other example of pictures widely reproduced and well-know by the public to the point it becomes an icon, everyone being free to put whatever he wants behing the image. I have 2 images in mind which could fit: Iwo Jima by Joe Rosenthal and the portrait of Che Guevara by Alberto Korda (certainly the most reproduced picture so far).

Any other example?
