The book “The magic ‘6’ of Borussia Dortmund” tells the story of the traditional German football club and the history of the city of Dortmund, which are closely interwoven. In the club’s chronology it is noticeable that many important events happened in years that ended with a “6” leading to the myth of the “magic ‘6’”. Each chapter starts with the city’s history marked by thick yellow horizontal lines, while diagonal running dates indicate the main sections of the BVB history. The decades in between are represented on yellow pages, in a layout turned by 90 degrees. Thus, this black-and-yellow guideline distinguishes between the club’s and the city’s history.
