Contrary to a popular urban legend, Northwestern's sports teams were never named the Fighting Methodists; before being renamed the Wildcats in 1924, they were just known as the Purple (as illustrated by the headline from The Daily Northwestern of October 1910). To celebrate the beginning of the new academic year, University Archives scanned a circular plaque bearing the teams' name and affixed its image to beverage coasters- convenient for hot drinks in the winter and cold ones for the lovely weather that we've been having recently.
