Mark Hill, the illustrator, has a fun project going on. If you send him your address, he will send you a random envelope that he has "doodled" on. These are wonderful. I got mine in the mail this week.... of course I'm going to do one to mail back to him (when I get back from Artfest, right now I've got no time). I've done stuff like this for friends and family, but never for complete strangers. Great way to promote himself. And I love getting stuff in the mail!
