Very good, VG+! The pre-hero Marvels are Strange Tales, Journey Into Mystery, Tales to Astonish, Tales of Suspense, and Amazing Adventures/Amazing Adult Fantasy, which evolved (devolved?) into titles featuring the Human Torch, Thor, Ant-Man, Iron Man and Spiderman. World of Fantasy 15 was dated Dec. 1958, and the final issue, 19, was dated August 1959. All 5 of these issues showed the same format, and contained art by the same artists, as the 4 contemporary pre-hero Marvel titles (Amazing Adventures 1 was dated June 1961).
