From Brooklyn Historical Society (click image to enlarge):
This month’s featured map was created by the Ohman Map Co., a New York-based map company located at 258 Broadway, in the early 1900s. One of only a handful of maps in the BHS Collection to show ethnic communities in Brooklyn, this map features various groups, from Europeans to African Americans to people of mixed heritage. It is clear from this map that early twentieth century Brooklyn was a diverse community of people, just as it is today.
