Sin City in full color?

While we're waiting for me to finish my write-up of Dark Horse Presents #58, I wanted to share something I noticed about the cover. At first, I didn't catch it...but there it is...a picture of Marv in full color.



I guess I didn't dawn on me at the time how rare that would become. I don't think I've ever seen a Sin City drawing by Frank Miller since then that ever had more than one or two colors in it. I'm going to have to dig through the rest of my DHP issues to see if there are any other full color Sin City pics waiting to be rediscovered.
