The Thing On Sputnik 4
I bought Race For The Moon #2 in July, 1958. I loved all things science fiction, and thought this comic was neat-o, daddy-o! I didn't know Jack Kirby's name, but I recognized his artwork from several other comics. "The Thing On Sputnik 4" was inked by Marvin Stein. The Grand Comics Database says the cover and the other three Kirby strips in this comic were inked by Al Williamson.
Race For The Moon #1 was an anthology science fiction comic drawn by Bob Powell, and issues #2 and #3 were by Kirby. It's a shame it only lasted three issues. It's hard to see why this cover of Race For The Moon wasn't at least as intriguing to comic buyers as issues of DC Comics' Mystery In Space.
