This two-issue set features the origin and evolution of Hydro-Man, one of Spider-Man’s classic elemental foes:
 
Amazing Spider-Man #212 – FN 6.0: First appearance and origin of Hydro-Man (Morrie Bench)! A rare Bronze Age key introducing a villain who becomes a mainstay in Spidey’s rogues’ gallery. A must-have for collectors of first appearances.
Amazing Spider-Man #217 – FN 6.0: Hydro-Man returns and merges with Sandman to become Mud-Thing, in a wild and bizarre team-up that only the early ’80s could deliver. Fun, weird, and unforgettable.
 
Both issues are complete, unrestored, and present well with solid eye appeal for the grade.
