A four-panel black and white comic. Some tough guy (you can tell because he's wearing a tank top) shouts, "You want me to fix you a knuckle sandwich??" Some other guy yells back "Oh I would love to see you try!!" The tough guy turns around and does something with his hands. He faces the other guy again and, somber-faced, reveals a sandwich on a plate with what looks like a fist between the two pieces of bread. Both of his hands are visible.
Another black-and-white comics page. The sandwich, on close inspection, isn't quite a single fist. Multiple bumpy ridges indicate several lines of knuckles at odd angles to one another. Dark, knobbly shapes are visible poking out from between the slices. They drip an unidentified liquid. The other guy holds the sandwich, apprehensive. Slowly, he brings it up to his mouth. His jaw opens. The bumps poking out of the sandwich look just the knuckles on his own curled fingers. He bites down.
