I hold that my quiz constitutes a review of the books that happens to be couched in the form of a quiz, since it makes the same sorts of points a review might typically make, and that the reprinting of excerpts from the strips in those books, in the context of my quiz and my review, is therefore permitted under the copyright notice, even without express permission.
Please do not copy or use the cartoons in violation of the copyright. For information, contact the official web site.
