Jacob and Wilhelm Grimm published their Children's and Household Tales in 1812, followed by a second volume in 1815 (German). But most people are not familiar with the first and the second volumes of the stories. It is much darker and more on psychological thinking. They were not regarded as suitable for children, both for the scholarly information and the subject matter.

I chosen few of the most famous story from the brother Grim and illustrated it. if you do some research of the stories, and look carefully, the illustration had included some darker side subject matter of the stories.  

I will put the link of the story below the illustration.
