Avengers #10, Nov. 1964: The Avengers Break Up!
The Lizard Collection contains 56 issues of The Avengers, going all the way back to #2. Here’s one of the earliest issues, #10, published in November 1964, with a cover by Jack Kirby and Dick Ayers.
Super-hero groups like the Avengers were always arguing and bickering and fighting among themselves, and in issue #10 it got so bad they broke up — but of course, they got over it in time for issue #11.
Our copy’s in good condition; not mint, unfortunately, but even with a little wear and tear this is still a pretty valuable book — worth a lot more than the 12 cents I paid for it in 1964.
