Creator owned comics are great. But they don't pay the bills.
Struggle on an indy book. Get recognized by editors at the big two.
Go work on one of the big two's titles. Get some name recognition.
Go back to creator owned when people know who you are. Sell more. Actually make enough to survive.
Lather, rinse, repeat.
To all the new talent coming onboard at DC, I say "welcome".
Who? I don't think I've ever even heard of this guy. I know all the others though.
Then you're clearly missing out on a great comic. "27" has currently been released as two series of four over-sized comic-books. It took me a few pages to really get into it, but it was worth all of the effort!
I do believe TP's are available of both stories.
