I Had That Comic: Februrary 5, 1987 Justice League 1 - Keith Giffen plots, @jmdematteis.bsky.social scripts, and Kevin Maguire pencils coalesce into the perfect superhero comic. If there's been an 80s cover referenced more than this one, I'm unaware of it.

I'd be willing to put a little money on Uncanny X-Men #136 (1980)/Crisis on Infinite Earths #7 (1985).

I Also Had These Comics: February 5 1985 Avengers 255 Marvel Fanfare 20 Strange Days 2 X-Men 193 1987 Watchmen 9 Vigilante 41 1988 Whisper 13 1991 Legends of the Dark Knight 16 1997 JLA 4 Preacher 24 How to Pick Up Girls if You're a Comic Geek

(sorry for the typo on February)
