If you have not checked out the auction at
debsliverlovers for Deb Mensinger's liver transplant recently, you should. There are some ridiculously amazing things available there, including prints and original art from some very well-known people.
If you have an affinity for the work of Thomas Canty and/or George R. R. Martin, you should probably go over there right now. Also, more cool things of this ilk will be posted soon. Keep your eye out.
