TODAY, SEPTEMBER 25, IS NATIONAL COMIC BOOK DAY — AND ITS ORIGIN IS KIND OF A MYSTERY.
Comic shops, publishers, collectors and fans across the country are celebrating National Comic Book Day today, recognizing a form of entertainment that went from cheap, disposable reading material to one of the foundations of modern pop culture.
But for a hobby obsessed with documenting first appearances, publication dates, creators and pedigrees, National Comic Book Day has one pretty big hole in its own history:
Nobody seems to know who created it—or why September 25 was chosen.
You'd expect a great origin story.
Maybe a major publisher declared it.
Maybe September 25 marked the release of some legendary comic.
Maybe Stan Lee climbed to the top of a mountain, raised a copy of Amazing Fantasy #15 toward the heavens and yelled:
“EXCELSIOR! SEPTEMBER 25 SHALL FOREVER BE COMIC BOOK DAY!”
😂
Unfortunately…nothing that exciting.
There is no clearly documented founder behind National Comic Book Day, and researchers haven't established a definitive reason September 25 became the date.
That's particularly funny considering comic collectors document everything.
We know when Superman first appeared.
We know when Batman first appeared.
We know the first appearances of Spider-Man, Wolverine, Harley Quinn and thousands of other characters.
Collectors can debate whether a barely visible character in the background of one panel counts as a cameo or a first appearance for the next 30 years.
But apparently nobody wrote down who invented National Comic Book Day.
And look at what we're celebrating.
For generations, comic books were folded, rolled up, traded between kids, stuffed into drawers and sometimes thrown away when Mom cleaned the bedroom.
Today?
They're bagged and boarded.
Pressed.
Authenticated.
Graded.
Encapsulated.
Displayed.
Collected as original art.
And some of those little books that originally cost 10 cents now sell for staggering amounts of money.
The characters inside them have also become the foundation for movies, television, toys, games, conventions and an enormous worldwide collectibles industry.
So today, September 25, we celebrate the comic book.
We just can't tell you exactly who decided we should do it today.
And somehow…
that might be the greatest unsolved mystery in comics that doesn't involve Batman. 😂
