Nancy Silberkleit, Co-CEO of Archie Comics, told me about this. What is a comic book fair? From their website:
The idea is simple. Your school agrees to host a Comic Book Fair on a school day, on an evening, or on a weekend afternoon. Whatever money is raised, your school collects 40% of the profits. There are no upfront costs and shipping is free! Family-friendly Archie Comics and Sonic the Hedgehog lines are included in your Comic Book Fair.
Awesome, right? Visit their website here.
