A fierce rivalry between Chicago’s North and South Siders comes to life each summer during the “Crosstown Classic,” when the Cubs and White Sox face off in their home stadiums. This unique series is loaded with team history and memories for both sets of fans, who hail from the North and South Sides respectively. Polaroids convey nostalgia, and there’s nothing that says nostalgia quite like baseball. The film format requires a level of intimacy not often seen in modern photo coverage of baseball games, when speed and instant images are prioritized.
