So I told you I've reading the trade paperback Flight lately with it's great collection of artists therein. Well here's the guy who is the creator, editor and most importantly does the covers: Kazu Kibuishi (wiki entry). I don't even know how to express how I feel about these images. They have the same kind of huge-beautiful-lonely-world feeling of blade runner. It's a futuristic alternate world with old romatic elements like steam powered machinery, blimps and trains (steampunk). Wonderful harmonious color palletes. He also makes the renowned comic Copper. I found the tutorial of his process for creating this comic fascinating.
