Most Expensive Photographs Ever

"You know the photo of Einstein with his tongue sticking out – we use it all of the time here at the _floss. One of the originals was sold at auction last month for a shocking sum of money, which made me wonder… what are some other insanely expensive photos that have sold at auction? And in the interest of full disclosure, Einstein’s doesn’t even rank in the top ten. But since he’s our mascot, I thought it was appropriate to throw him in the mix."
