Brick by Brick
I just purchased the $5 PDF of this book from McCraine’s website Doodle Alley. You can read most of the visual essays on his site, but I was so impressed with what I saw that I bought the book. It’s 208 pages of insightful observations on being an artist and making creativity a sustainable practice told in comic book form. Definitely a must read for anyone in a creative field dealing with the joys and frustrations of the artistic process.
