I mentioned the DC animation licensing work toward the end of the conversation.

The way he explains it on his site is I guess most licensing companies use this sets of images/designs that he (and presumably others) drew up as the base for their licensing efforts.
Wood is right. DC/WB sends out style guides full of character artwork, backgrounds, logos, and other graphic elements to be used for all the licensed products.
As a t-shirt designer, we have TONS of style guides here at work. The DC stuff has always been amazing, especially the core Batman and Superman lines. And now I know why: They're drawn by MIKE ZECK!
I've been using his artwork for YEARS and never knew it was him because WB does not name the artist in their style guides.

I know Ryan Sook does a lot of licensing stuff, so I thought most of that stuff was him, but I guess I was wrong.
Thank you Wood. You've answered one of the great nagging questions in my life. It's like you named 100 song titles that were JUUUUST on the tip of my tongue.

And tell me that's not some of the finest constructed figure work you'll ever see. They look even better with fully-rendered coloring.
