Fantastic 4 Comic Covers

Identify this coverless Marvel please?
There is no publication info, it must have been printed on the inside cover. There are four stories, ranging from monster, to sci-fi, to suspense.
1. Mister Morgan’s Monster ~Kirby & Ayers
2. The Day Before Doomsday! ~Kirby & Ayers
3. The Man in the Glass Cage! ~Don Heck
4. A Switch in Time ~Lee & Ditko
If the caption ads at the bottom of the pages are correct timewise, then there is a small window of when this book could have been published. I’ll explain.
At the end of the last story, the bottom caption reads “LIKE THIS TYPE OF STORY? THEN DON’T MISS AMAZING ADULT FANTASY COMICS — ON SALE” At the centerfold page, there is a caption that reads “yOU’VE NEVER READ A COMIC LIKE THE FANTASTIC FOUR! GET YOUR SPINE-TINGLING COPY TODAY!” Since the first issue of FF was published in Nov. of ’61, and the last issue of Amazing Adult Fantasy was published in July of ’62, I assume the book in question was published somewhere in between. Hope that helps.
Googling around, it appears to be Strange Tales #99.
