Thank you to Curbed for this article about the Mapping Brooklyn exhibition at the Brooklyn Historical Society. This map shows what the rents were for homes in 1940s Brooklyn, block by block. $100 was very expensive in the 1940s and was equivalent to about $1700 today. The exhibition aims to, “introduce visitors to the remarkable range of historic maps that have sought to study and document facets of the borough to contemporary art works that reveal mapping as a powerful means of representation.” The exhibition runs through May 3rd. Brooklyn Historical Society is located at 128 Pierrepont Street, Brooklyn, NY, 11201 at the corner of Clinton Street in Brooklyn Heights.
