I got a lot of really great books at SPX this year, but of the ones I've read so far, this is my favorite: Hilda and the Midnight Giant by Luke Pearson, published by Nobrow Press. Charming story, drop-dead gorgeous cartooning--what's not to love?!
Yeah, the whole thing is really beautiful. Interestingly, the line art is not quite black...it's maybe a deep blue/purple on most pages. It's very subtle, though. I didn't even notice it for the first few pages.
