From Kraven’s Last Hunt, a Spider-Man story from 1987. I was intrigued by some pages I saw posted elsewhere on tumblr so I tracked down the book. I wasn’t disappointed. Kraven (and Peter Parker) spend a lot of time naked or shirtless in these issues.
The story is also super dark and creepy, with Kraven burying Spider-Man alive and assuming his identity. His psychology is explored a lot so you can understand just how majorly cray-cray he is.
