Sir Gawain and the Green Knight as a new comic-book, November 2021.

A glowing review indicates that the unpromising cover does not reflect the fine interior artwork.

It’s not on Amazon but elsewhere I found out that it’s 44 pages in total and, with the above review mentioning the long footnoted essay at the end… it’s not actually the graphic novel I initially thought it was. Still it looks excellent, if you can get past that cover, and is just £5 direct from the author. I assume it’s a paper booklet-comic, but it might be digital at that price.
