Jack the Ripper’s London. This extraordinary map details the levels of poverty in the infamous slums of Victorian London’s East End in 1887. Each street is colour coded running from black, “Very poor, lowest class … vicious, semi-criminal” through blue, “Poor, casual … chronic want” up to red, “Well-to-do”.. The concern over poverty and social conditions in this area of East London was duly manifested in the year after this ground-breaking map was created, with the series of horrific killings that became known as the Whitechapel Murders. As the first socio-economic survey undertaken anywhere in the world this map is now considered an infographic icon. £6,500
