To me this is a very significant title amidst two others.
My starting date for collecting Silver Age Marvels is with the return of Kirby full-time to the "company with no name" and Strange Worlds #1 Dec. 1958; Tales to Astonish #1 Jan. 1959 and Tales of Suspense #1 Jan. 1959 --- all September 1958 releases.
Strange Worlds #1
"I Discovered the Secret of the Flying Saucers"
Lee, Kirby & Rule
"I Captured the Abominable Snowman"
Lee & Ditko
"I Am Robot"
Lee & Heck
Tales to Astonish #1
"We Found the Ninth Wonder of the World"
Lee, Kirby & Rule
"I Know the Secret of the Poltergeist!"
Lee & Ditko
Tales of Suspense #1, January 1959
"I Dared Explore the Unknown Emptiness"
Lee & Heck
"Prisoners of the Satellites"
Lee & Ditko
Kirby joins Ditko and Heck ---and the three, with Lee, begin to ramp up to the Marvel Age: science fiction becomes fantasy and fantasy in Nov. 1961 becomes the fantastic.
