This 1979 Chicago Police Department General Information Handbook is a fascinating piece of historical memorabilia. It offers a glimpse into the inner workings of the police department, with sections including a detailed street guide to the city, a schedule of days off, a calculator for determining "time due" (overtime hours), a telephone directory to the department's in house phone network as well as a list of "Miranda Rights" questions to ask a suspect before interrogation. The handbook was published by the organization itself and is a must-have for police collectors or anyone interested in law enforcement history. The handbook is in good condition and contains no markings or signatures. It was manufactured in the United States.
