A very unique Calvin and Hobbes site. Before going here, go to the wikipedia entry if you don't know the history of C&H. This site has an enormous gallery of bootleg C&H merchandise, tattoos, and items that you won't see in stores. [L]
Likely the most updated and maintained C&H website on the web now, Kim's Calvin and Hobbes Page is a great site full of every resource you can imagine. [L]
Though the original intent of the site (to be a huge links page) is now moot because of tons of dead links, the site is the one place that features a radio show from CBC Canada in which fans talk about Calvin and Hobbes' end.
