Cover art. Amazing unconscious carry scene! Artist is Yanick Paquette.
The story actually has a head KO, but I don't think it's very good. The art inside is a grittier style.
I have high res scans you can check out. I am going try something different. The new scans are on Amazon S3. They are too big to store on my site.
