Cartoonists have long used their art form to tell stories and illuminate truths in novel and vivid ways. Take artist Eddie Campbell, who teamed up with writer Alan Moore in 1989 to publish a historical cartoon series about the 1888 murders of London sex workers by the notorious Jack the Ripper. The collection, later published in its entirety as the graphic novel From Hell, was more than just a speculative retelling of horrific true crimes. It was also a scathing indictment of the injustices of Victorian society, where the lives of poor and marginalized women barely registered in the minds of Britain's ruling class. This week, the third annual Non-Fiction Comics Festival in Burlington celebrates fact-based graphic storytelling, including Campbell's, through such genres as personal memoirs and diaries, science-based comics, political cartoons, and graphic medicine. The weekend-long event, presented by Vermont Folklife and the Fletcher Free Library, will also feature workshops, panel discussions and exhibitions by more than 40 cartoonists from around the country.

Zuppo noted that attendees are traveling to the event from as far away as Los Angeles. This year's festival will also highlight the relationship between comics and other forms of visual storytelling, such as video games, role-playing games and pinball, Zuppo said. One panel discussion will feature Brian "Box" Brown, a cartoonist who produced the 2016 graphic book Tetris: The Games People Play; Vermonter Jon Chad, who penned the 2022 Pinball: A Graphic History of the Silver Ball; and Steenz, a St. Louis-based cartoonist and professor who wrote 2024's Side Quest: A Visual History of Roleplaying Games. How did Vermont Folklife, a statewide history nonprofit, get involved in an event focused on cartooning? "Our interest is really in exploring the potential of comics as a…
