Though I've said earlier that most readers of popular fiction are attracted to that form precisely because it doesn't require them to evaluate it, it's inevitable that a few readers will form their own "canons" for these sort of anti-canonical works. It's inevitable because no matter how simple or how debased a given popular genre may seem to elitists, some creators will invest considerable passion and imagination into those works.
I once said I'd try to formulate a list of "adult pulp" comic books, but never got around to it. But of late I've been cogitating on pulp magazines (and some of their contemporaneous fellow travelers). Since these were the predecessors of comic books, here's my list of some above-average popfic tales from the pages that gave birth to many of America's most lurid and extravagant dreams.
Edgar Rice Burroughs-- TARZAN OF THE APES and THE RETURN OF TARZAN (Tarzan series), GODS OF MARS and MASTER MIND OF MARS (Mars series)
H.P. Lovecraft-- THE CALL OF CTHULHU and THE WHISPERER IN DARKNESS
Robert E. Howard-- "Tower of the Elephant" and HOUR OF THE DRAGON (Conan), THE MOON OF SKULLS (Solomon Kane)
A. Merritt-- THE MOON POOL and THE SHIP OF ISHTAR
Clark Ashton Smith-- the "Zothique" cycle and THE HASHISH-EATER
Lester Dent-- THE LAND OF TERROR and THE MUNITIONS MASTER (Doc Savage)
Seabury Quinn-- THE DEVIL'S BRIDE
Sax Rohmer-- THE INSIDIOUS DOCTOR FU MANCHU and BROOD OF THE WITCH-QUEEN
