Harold sez, "In this post on Neil Gaiman's blog, he forwards an offer from Cerebus creator Dave Sim to send anyone, for free, and autographed copy of an issue of Cerebus where he parodies Gaiman's 'The Endless.'"
And if you're wondering what the catch is, it's this: Dave wants to know (as, I have to admit, do I) how many of the people out there in internet-land will actually go and do things that don't involve passively clicking on a link and going somewhere interesting. So what you have to do is write Dave a letter (not an e-mail. Dave doesn't have e-mail) telling him that you read that he'll send you a signed Cerebus, and telling him why you'd like him to send you a copy. It's as easy as that. And, quite possibly as difficult.
