Let’s take a step back in time to 1911, when a brochure was published featuring Cook County, titled ‘Her resources and possibilities. The opportunities offered to Home seekers.’ This historical document provides a unique insight into the county’s past. Building a school was significantly cheaper in 1911, as evidenced by the picture of the Cook County High School building and its construction cost of $35,000. Today $35,000 converts to between $1,225,801.85 or as much as $2,603,272.38 in relative value according to Measuring-Worth.
