Amazing Spider-Man #23 — Signed by Stan Lee, Steve Ditko Art (1965)

Amazing Spider-Man #23 stands at the centre of the Silver Age, the moment in which the superhero ceased to be a genre and became a narrative form capable of adult tension. Written by Stan Lee and drawn by Steve Ditko, the issue carries the third appearance of the Green Goblin, the villain who would become Spider-Man's defining antagonist — and, in the hands of these two authors, something more unsettling than a simple adversary.

The drama of the number is psychological before it is physical: the Goblin's rise is staged as a slow tightening around Peter Parker's double life, and the mask becomes the story's real subject. Ditko's cover compresses that tension into a single graphic gesture, with a decisiveness of line and a control of composition that made his work on the character the visual benchmark against which later interpretations are still measured.

This copy, graded 6.5, is additionally signed by Stan Lee, whose autograph places the book in direct contact with the author who co-created Spider-Man and shaped the voice of the Marvel universe. For a 1965 issue, that combination of grade and signature is rarely encountered: the signature alone converts a key Silver Age book into a document of authorship, and it is precisely this double status — historical artefact and signed object — that collectors of high-grade Marvel material pursue.
