Sub-Mariner #16

Marie Severin and Frank Giacoia conjure a genuinely eerie tableau for this 1969 Marvel gem — Namor rises dripping from seaweed-choked waters in the foreground while, behind him, ghostly ships from wildly different eras loom out of the murk alongside a massive, snarling spectral face. The tagline "The Sea That Time Forgot!" promises a voyage into something stranger than the usual undersea adventure, and the cover's haunting atmosphere delivers that sense of dread with quiet confidence.
