What, you think people are going to notice what comic book this is? On their little black-and-white TVs? And even if they have a big color job, it just goes by in a flash. Plus it's *a comic book*. Who cares? Nobody. I'm not wasting any sleep over it.

The screenshot is from “Der Tag,” M*A*S*H, S4, Ep17, aired January 1976. It's the one where Hot Lips is away, Frank bothers everybody, so Col. Potter asks Hawkeye and B.J. to be nice to him. Frank winds up: cleaning up in poker, getting drunk, professing a romantic interest in Nurse Kellye. He also stumbles into an ambulance (with a jokey toe tag on his foot) and winds up at the front. Joe Morton guest stars.

The comic book Radar is holding is Avengers #60 from December 1968. Avengers #1 was published in Sept. 1963, or about 10 years after the end of the Korean War. But yeah, I'm sure they thought, “Close enough. Who's going to notice? And who's going to know?” Turns out, nerds. Lots and lots of nerds.
