I was reading Moore and Gebbie's story in the 9-11 benefit book and I noticed that it was dedicated to underground comix artist Jim Osbourne.

I was wondering about the reason for this dedication, i.e. has Mr. Osbourne passed away? If he has, that's really sad news and I wonder why it wasn't reported on the comic news sites (if he hasn't, I hope this post doesn't start any unfounded rumors). Does anyone know?
