The Feiwel and Friends Fall 2010 catalog is accessible online here. You should give it a look. It's really a beautiful catalog and there are some terrific titles coming out (but, then again, I may be biased).
This is the back cover of the catalog, a no-text cover image from The Marbury Lens. I think it looks amazing. And I've seen some of the other art elements that are going into the jacket design, too... and I just have to say this is one of the overall coolest cover concepts ever.
