Kassel is the birthplace of the Grimm Brothers, the world famous collectors of fairytales and etymologists of the German language. Their heritage is being shown to the public in the Grimm Brothers Museum. One of these fairytales is "The Wolf and the Seven Kids". The relevant passage tells us about the way the kid goats escaped from the stomach of the evil wolf: "But the mother said, 'Now go and look for some big stones, and we will fill the evil beast's stomach with them while he is still asleep.' The seven kids quickly found some stones and put as many of them into his stomach as they could get in. The mother sewed him up again with greatest haste, so that he was not aware of anything and never once moved. When the wolf at last awoke, he got up. The stones in his stomach were making him very thirsty, he wanted to go to a well to drink. But when he began to walk and to move about, the stones in his stomach knocked against each other and rattled. Then he cried, 'What rumbles and tumbles against my poor bones? I thought 'twas six kids, but it's only big stones." The product depicted here is a bag in the form of a caricatured wolf. It is supposed to be sold as a souvenir in the museum’s shop, filled with sugarcoated candy in the shape and colour of pebbles. After consumption of the candy it can be used as a pencil case.
