Spidey-Man

A curiosity born from the Silver Age's most visually electric era, Spidey-Man made their debut in Jim Steranko's legendary Nick Fury, Agent of SHIELD #3 in 1968 — a collector-beloved run if there ever was one. With appearances spread across Capt. Savage and His Leatherneck Raiders and The Amazing Spider-Man Omnibus alongside such recognizable Marvel faces as Peter Parker, Spider-Man, and the Green Goblin, this character occupies a fascinating corner of Marvel's sprawling universe. Rare enough to count appearances on one hand yet persistent enough to surface across 44 years of publishing, Spidey-Man is exactly the kind of deep-cut discovery that reminds you why digging through Marvel's back catalogue is always worth it — and yes, one of those few appearances carries key-issue status for the sharp-eyed collector.
