In regards to some of the photos with Slender Man in the backgrounded with children and the group of people, “He is known as a kidnapper and killer of children. A few photos of him exist.” As for my post with the German pictures, they are both from Hans Freckenberg, with his woodcuts, type of pictures, being dated to the 1540’s. I found some quotes, from a guy who was saying the quotes, that im going to share. http://grcade.com/viewtopic.php?f=7&t=13390&start=60
A german woodcut from the 1540s. It has puzzled historians since it was discovered at Halstberg castle in 1883. The woodcut bears the distinct style of a known woodcut artist from that area, Hans Freckenberg. Although know for his realistic depiction of human anotomy in his works, something that was unusual for the woodcuts in the 16th century, this picture differs radically from the rest of Freckenbergs works. The character to the right bears little semblance to a human being, with skeletal physique and long limbs at odd angles. Many theories have been dicussed as to what Freckenberg wanted to symbolize with that character, some say its a personification of the religious wars that raged in Europe at the time, others say its a personification of the mysterious plague that have been believed to be the reason for the mysterious abandoning of the Halstberg castle and the nearby village in 1543.
