As self-serving as this seems (and I am genuinely uncomfortable with it), I would like to recommend my art book of science fiction caricatures. Heroes and Villains is a caricature art book with over 30 color and black and white illustrations of science fiction's best and baddest from television and the movies. It is available on Amazon. I have a Facebook
page for the book and more artwork can be seen at my DeviantArt
page. Thank you!
