Here's the inside of the back cover. I'm pretty sure that the if the age group these ads were aimed at is still reading SF, it's tie-in books or fantasy of some kind.
"Minister without Portfolio" by Michael Fischer (another writer I'm unfamiliar with) is one of those "aliens visit earth" tales with a twist ending that I'm sure I would have loved in 1954. Even now, I think it worked okay.
The experimental story in the issue is Stan Baer's "Night File," which is told entirely through teletyped news stories and the operators' comments. New wave, anyone? I don't know Stan Baer's work, which makes his the third of the six names I didn't recognize in the ToC.
