Every day this month I will share with you the first (at least as far as I know) U.S. professional work by a notable comic book creator. Here is an archive of the creators who have been featured so far.
Today's featured creator is Joseph Michael Straczynski!
"JMS" is a bit of an aberration, as he was already quite a successful writer in all sorts of different media before he wrote his first comic book story, but hey, still, it is his first comic book story!
That comic was August 1987's Teen Titans Spotlight #13, with a clever tale pitting Cyborg against...Two-Face?!?
DC really ought to reprint this story. Otherwise, I recommend you tracking a copy of the issue down. It's a good read.
Straczynski wrote a couple more comics in the early 1990s and then, after creating Babylon 5, he came back to comics in a big way with Rising Stars, Midnight Nation and Amazing Spider-Man. But his first comic work was 23 years ago!
