Marc Nathan opened his Baltimore-based comics shop, Comics, Cards, and Collectibles, in 1994. Five years later, he launched the Baltimore Comic Con, one of the top fan-favorite comic book conventions in the country. In 2017 he instituted the Ringo Awards, an annual celebration of the year's best comics and the people who make them. And on top of all that, he was once the mascot for a popular major league baseball team! Now that's a resume.
