Issue #111 in my comic book cover collection features the maze of a Lynx and is titled The Lynx Files. I used a simple matching plain background for this book, I guess we could call it monochromatic. I think it is my first monochromatic cover in the collection.
My comic book cover mazes are archived by year:
