Lucille by Ludovic Debeurme and I think that was the best book of my trip. I started reading Big Questions by Anders Nilsen, too but didn't have time to finish it. I do want to get that book though. They were both fantastic. In fact, I was just thinking about Lucille again yesterday on the drive home.
More comics about the Cartooning Studio workshop I went to in Vermont at the Center for Cartoon Studies. You can also buy the whole book with these comics and the two mini comics I made during the week: Cartooning Studio 2013.
