Bantam Books has published The Rocky and Bullwinkle Book by Louis Chunovic, as well as Fractured Fairy Tales by A. J. Jacobs.
The Frostbite Falls Far-Flung Flier, formerly published quarterly, is an unofficial zine devoted to Rocky and His Friends, The Bullwinkle Show, and other Jay Ward cartoons. Thirty-nine issues have been published, and I still plan to put out Volume 10, Number 4. It's over four years late, but don't give up hope. In the meantime, back issues are available.
Charles Ulrich, webmaster of the Frostbite Falls Page and editor of the Frostbite Falls Far-Flung Flier, now writes a column on Jay Ward cartoons for Animato! magazine.
