A rare pocket map guide to Chicago before the Great Fire of 1871

A rare depiction of the city before the Great Chicago Fire of 1871 destroyed over three square miles of houses. The guide contains lists of public ameneties, including streets, railways, schools, churches, saving institutes, telegraph companies, Artesian wells and asylums. This is an early example, still with the 'Chicago Driving Park'. a horse trotting venue, located astride Lyon Avenue in the lower right of the plan. We have not been able to trace an example with an earlier date.
