Someone who agrees with me, that the Lee/Ditko story in AMAZING SPIDER-MAN ANNUAL 1 (1964) is arguably
the best annual ever published.

In a story that combines 6 of Spider-man's villains as "The Sinister Six", and in the span of a 41-page story fits in cameos and solicitation for every series in the Marvel line at that time. And also manages to fit in 6 full-page pin-ups within the story, of Spider-man fighting one-on-one with each of the 6 villains.

The above link gives a sampling of 20 of the 41 pages.
