This six page Kirby/Ditko story is reprinted from FANTASTIC FOUR ANNUAL #1 (1963) (not AMAZING SPIDER-MAN ANNUAL #1, as it’s mistakenly cited on the first page of this reprint). A bit of an oddity, as it retells a scene done in two pages in the first issue of AMAZING SPIDER-MAN earlier that year, with full Ditko art, where Spidey breaks into the Baxter Building, thinking he could get a job with them. He was a bit unclear on the concept early on, I guess. The Avengers might have been a better bet if they’d formed by then.
It does feel a bit stretched, with the attack from each FF member (taken straight from the original) being followed by another attack newly revealed for this telling. It’s still interesting, especially the way Kirby draws the Spider-Man / Mr. Fantastic battle.
