92-812 JAMES BLISH Giants in the Earth (c. 1952) and ROBERT SILVERBERG We, The Marauders (c. 1958; January 1965; 1st thus)
Note this volume has a split artwork cover for each story and that the volume is headlined as "A Pair From Space." Please note that the publication history of these stories is suggested to be "first paperback publication" as well as "complete." Probably this relates to the complete abridgment of stories for paperback publication and forestalling any potential hesitation on the buyer at the newstand. I have also found that in the Belmont Books catalogue this volume is listed as B92-812 A Pair From Space by James Blish and Robert Silverberg, rather than the individual titles.
B50-670 E. B. MANN Buzzards of Apache Gap and E. B. MANN Return of the Gun-Cub (1966; 1st thus)
Note that Belmont followed a similar format of two stories by the same author as did ACE Doubles for the G-series mystery and the later five-digit numerical sequence science fiction genres. Split artwork cover.

Split artwork cover.

B50-788 KRIS NEVILLE Special Delivery (c. 1951) and DAVE VAN ARNAM Star Gladiator (October 1967; 1st thus; listed as "complete novels")
Split artwork cover. The artwork for Star Gladiator reminds me of the Jack Gaughan cover for Andre Norton's Star Born.

Note the move to a single art cover.
