The first fantasy fiction magazine edited by Lester Del Rey, who would later edit the first short run of Worlds of Fantasy, then have a sustained run as the fantasy-fiction editor at Ballantine, then officially Del Rey Books. All four covers are by Hannes Bok.
The horror title from Great American Publications, also including The Saint Magazine and Fantastic Universe, newly acquired (and the latter soon folded). Only two issues were published.
Shock Tales, Suspense (both 1959); Thriller (1962)
Myron Fass, one of the more prolific publishers of exploitation magazines over the latter half of the 20th Century (and perhaps best remembered as the producer of some of the more durable imitators of Warren Publishing's Creepy and Eerie with his Eerie Tales line of black & white horror comics magazines in the latter '60s and early '70s), apparently is responsible for these magazines, the first two more or less the same magazine (and perhaps the only issues published, even though Suspense is labeled #4), and the last having three known issues...all with similar amateurish photography as the interior illustration for what can be called "confessions-style" attempts at horror fiction, perhaps masquerading clumsily as true accounts. Note model recurrence.
