Living up to the hype, Defenders #9 did indeed take the non-team "Sideways into 1967!" The trip landed the Defenders on a parallel Earth a handful of decades in the past, bringing a version of S.H.I.E.L.D. agent Nick Fury from the 1960s into the larger storyline around the reality-bending Concordance Engine.
Though pictured on the cover, Sub-Mariner did not partake in the issue.
With that segue, here's a look at four striking covers from comic books published in 1967 that did spotlight the Prince of Atlantis!
Dedicated to the definitive superhero non-team.
