Slender Man - Ninth Image, June 14, 2009
This is an image of four hikers who later died under mysterious circumstances in the Dyatlov Pass in Russia in 1959. This copy has been altered to included the figure of the "Slender Man" in the background, as an implied answer to the mystery of their deaths.
This copy of the image comes from the Original Slender Man Mythos website [Link Here]. Compare to the unaltered copy of the picture below, taken from the Awesome Robot website [Link Here].
