In case you haven't heard, Dave Sim has made his first two "phone book" sized volumes of Cerebus available as a free PDF download (optional donations accepted). Also included is an audio/video adaptation of the first five episodes of his High Society story.

The first 185 issues are some of the greatest comics ever produced, and the final story shows just how good an artist he is. I also really like Glamourpuss despite the oddness of it all.
