Sea Devils #7

Four daring adventurers in red diving suits are literally being held aloft by a churning, sentient wave — and one of them shouts the alarming truth right on the cover: "This wave that's holding us up — it's alive!" Russ Heath's cover art makes the threat feel genuinely unnerving, the foaming water rendered with an almost organic menace as the Sea Devils struggle against its impossible grip. Billed as a book-length undersea spectacular, this October 1962 DC issue promises a full-issue showdown with "The Human Tidal Wave" — and that cover alone makes a compelling case for diving in.
