Montreal's outdoor comic book festival is putting page to pavement in May, with a pedestrianized art stroll along 1.2 km of rue Saint-Denis and a super-powered lineup of free activities, exhibitions and artist encounters. More than 250 cartoonists from around the world are set to attend the Festival BD de Montreal (FBDM) from May 26 to 28, including some big names in the industry from Instagram-famous Sarah Andersen to Gabriel Bá and Fábio Moon of The Umbrella Academy.
