The idea of comic books as "dangerous literature" is usually discussed in terms of "mature" material being distributed in a child-friendly form, but consider this more frightening definition: according to the GCD, blacks were told to memorize and destroy this comic to avoid being lynched for possession of it.
This is not just another day off from school, from work, vacation day. Honor the man, his spirit, his work, and his fellowship, by remembering, discussing, acting upon his words and deeds. We who collect comics do dearly love our heroes, and they don't have to come from a doomed alien world or dress up like insects to inspire us and change the world.
