DC Comics asked me to do a couple of designs back in 1999 to firmly establish a look for the Gotham City police force and Batman for all the artists drawing the book to reference. That didn't last long, haha. Artists want to draw Batman their way. Which, I totally understand.
I loved these! I remember seeing them in a Wizard mag around the time of the big re-design of the Bat-books! There was one with the Batmobile too which looked sick! Do you still have that one? You should post it! I would love to see that again!
