"Der Struwwelpeter" by Heinrich Hoffmann is a German children's book written and illustrated in 1845. This collection of ten illustrated and rhymed stories presents cautionary tales about children whose misbehavior leads to disastrous consequences. Each story delivers a clear moral lesson through exaggerated scenarios, from a boy who refuses to groom himself to children who ignore warnings with shocking results. Considered a precursor to comic books, this influential work combines visual and verbal narratives to teach lessons through darkly humorous tales of disobedience.
