Sea Devils #15

From the depths comes one of Silver Age DC's most delightfully strange threats — a colossal spider-like creature lurking beneath the waves, its web ensnaring a submarine while the Sea Devils in their distinctive diving gear fire back in a desperate bid to break free. Russ Heath's cover for this February 1964 issue delivers both the spectacle and the tension perfectly, with the speech balloon — "We've got to stop this undersea hunter from reaching the sub caught in its spider-trap!" — making the stakes crystal clear. Billed as a "thrilling new book-length sensation," Ed Herron's "Secret of the Sunken Sub!" with art by Irv Novick promises an underwater adventure that earns every word of that billing.
