Since the book is focused on analyzing the manga I thought that we could show that aspect of it by using pen-like scribbles and annotations on the cover (as well as a few toxic particles from the manga itself). This way the reader has a clear idea of what the book will be about.
This screenshot from the movie encapsulates the Nausicaa world perfectly so I upscaled it to make sure it stays print-ready in a larger size.
I couldn’t resist combining the barcode on the back with The Mehve (a glider from the manga) - it looks like it’s flying! :)
