The Ralph Hargrove Photograph Collection consists of one-hundred-thirty-six black-and-white photographs of Jackson, Mississippi, from 1927 until 1984. Most of the images were taken during Hargrove's forty-year career with the Jackson Police Department. Subjects include city government buildings, police department activities, and state and national politicians. The collection features images of the rifle found at the crime scene after the murder of Mississippi civil rights leader Medgar Evers, Jackson's first African American policemen, U.S. Senator John C. Stennis, Mississippi lieutenant governor Charles Sullivan, Alabama governor George Wallace, and a Jackson city vehicle known as "Thompson's Tank."
