We have all heard that old saying, and I was wondering, in an adult Science Fiction, would it be okay to have illustrations. I remember reading H.G. Wells or even Edison's conquest of mars and seeing drawings on pages here and there. Would you consider it a crutch, or a cop out, or are illustrations something that are still done, and if so what precautions should be taken when using them? I come from writing comic books and have a few very good artists wondering if I would be interested in them doing work on my novel.
