Gods' Man

4 stars: loved this book, would recommend
Public domain as of this year!
It has no words, so I wasn't sure if I wanted to track it. I came across it because I was looking for books that were public domain that have interesting images to use, and so I ended up reading through it.
It's a wordless novel, the precursor to graphic novels and comic strips. Apparently this was a whole thing in the 1920s and 30s. The art style is pretty cool - extremely dramatic woodcuts, making a lot of use of unusual perspectives, dramatic facial expressions and so on - I don't know enough about art to comment on it. I think it's worth a read (?) just because it's an interesting look at the very beginning of the medium.
Edit: you can read it here, though some of the images are split across PDF pages: commons.wikimedia.org/w/index.php?title=File:Lynd_Ward_-_God%27s_Man.pdf
